In response to @Chukarhunter, my prior description may not have been clear on a few details.. We took delivery of Hull #990 on 2/17/22. I installed the Truma 12 VDC powered anti-freeze option immediately following delivery, while at the Oliver factory campsite. Since the nighttime temperatures were then in the low 20s and we planned to be in transit over the next 10 days or so, I expected the DC powered "anti-freeze" option to protect the water heater. I was not previously aware of a plug for the exhaust port of the Truma water heater. I separately purchased the antifreeze unit, which I understood to be the same as installed by Oliver. I don't recall any mention of a plug in the installation instructions. When we returned home to Dallas, the temperatures were still below freezing during nighttime, so I fully winterized the water system, following the instructions in the Oliver owners manual, including draining the water from the Truma water heater. I did close the water inlet valve to the Truma, to prevent the RV antifreeze from entering the unit. Following the winterization, several weeks later I moved the trailer to an enclosed storage facility, where I turned OFF both the propane and lithium batteries. Since the water had been drained from the Truma water heater, there did not appear to be any reason to continue to provide 12 VDC power to the Truma antifreeze unit. At the start of our recent road trip, I flushed the RV antifreeze upon arriving at the campsite for our first night. I turned on the propane, then turned on the Truma water heater, first at the external switch on the unit, then at the internal/remote control inside the trailer. As described above, the internal/remote control did NOT show an amber light and the water heater would not operate. Based upon my interaction with the Truma authorized service provider, who conveyed instructions from Truma, I don't believe the reason the water heater would not operate had anything to do with winterization processes. Truma indicated the problem was the result of completely shutting down power to the water heater control circuits by turning OFF the lithium batteries. In the next week or so, I plan to again put the trailer into the storage facility and turn OFF the propane and lithium batteries. When I retrieve the trailer from storage for our next trip, I expect I will encounter the same issue, where the Truma internal/remote control does not show an amber light without repeating the steps listed in the prior post. I appreciate your comments and will investigate the plug for the exhaust port of the Truma water heater.

My wife and I pickup up our LEII, Hull 990 on 2/17/22. We spent the nearly a week at or near Oliver's operations in Hohenwald shaking down the systems before returning to our home in Dallas. Our Truma water heater worked as expected and we marveled at how it was "just like out tankless water heater at home". I winterized the trailer upon our return home, including installing the antifreeze option for the Truma water heater. Our LEII spent the next 6-7 weeks in our driveway while I made additions to it. On April 23, I moved the trailer to an enclosed storage facility approximately 30 miles north. We have three Lithionics batteries, for which I followed the recommendation to turn OFF the batteries during storage for 30 days or less. On approximatly May 8, I retrieved the trailer from the storage facility to prepare for departure on May 11 to South Carolina. Everything appeared to be in order prior to our departure, although I did NOT test the Truma water heater. After a full day of travel, late on the night of May 11 I discovered the Truma water heater would not operate. We had two full 20 lb. propane tanks, the stove easily lighted verifying the flow of propane. I verified the power switch on the Truma unit was ON, however, the interior control located to the right of the pantry did NOT display an amber light. No hot water. I contacted OTT Service the next day and was advised to check the fuse, which proved to be OK. I was also advised to check for 12 volts DC at the rear of the Truma remote control. Today I removed the access portal from the forward interior wall of the pantry to discover the Truma remote is apparently epoxied to the hull. A black cable with an RJ11 type telephone connector plugs into the rear of the Truma remote, making testing for 12 VDC difficult. I again called OTT Service, and after four hours have still not received a call back. I searched Google for "Truma service near me" (now Paris Mountain State Park, near Greenville, SC) and found the Truma Dealer Partner Locator on Truma.net. The first listing was for Retromodern Campers, in Pickens, SC. I phone them and spoke with Scott Whitmire, who indicate his company had recently become an authorized servicer for Truma and he had been installing Truma units in refurbished trailers, many from the 1940s and 1950s. After describing the symptoms of our Truma unit, Scott indicated he had encountered the same symptoms twice, once as recently as two weeks ago. He said he would call Truma for guidance. In about 10 minutes I received a return call from Scott, saying he had spoken with Truma and received the following directions: Power ON the Truma unit at the main power switch. On the interior mounted remote control, turn the dial to OFF Wait a few seconds, then turn the power to ON at the remote control The remote control unit should now display the amber light on the dial. I was pleasantly surprised the amber light came on. I went outside to the external shower (not wanting to fill the gray tank) and ran the water for less than a minute, when hot water began to flow. I then verified hot water was available at both the bathroom and kitchen faucets. Scott said as long as the power is not shutoff to the Truma unit, it should work just fine on the next trip. I point out that I expect it to be common practice for Oliver owners, many of whose whose trailers are equipped with lithium batteries, to power the batteries OFF between trips. This will necessitate performing the Truma re-boot process described above after each storage period in which the lithium batteries are turned OFF. I can find no reference to this re-boot process In the Truma section of the 2022 Oliver Optional Features Component Manual. I hope others with lithium batteries and Truma water heaters will recall call this procedure after they have turned OFF their lithium batteries during storage.

Correct. 2022 models of LEII trailers are equipped with Never Lube axles. I specifically avoided purchasing a 2021 model to avoid the frequent maintenance required of the earlier bearing type. I am relying on Oliver product documentation that my trailer (Hull 990) is so equipped.

I recently installed the TireMinder i10 TPMS system. The instruction manual says the following of page 28: Can Rubber Valve Stems Be Used with The TireMinder Transmitters? Yes, TireMinder Transmitters may be used on high quality, high pressure rubber valve sterns. However, we highly recommend brass or stainless steel valve sterns. Due to the fact that rubber valve sterns deteriorate fairly quickly, e.g. they should be replaced when replacing your tires, an external TPMS sensor can exacerbate the deteriorating by adding weight to the valve stern. Additional rubber valve stems issues are based on age, length and physical location (i.e. exposure to road salt, high heat, sun, etc). If using rubber valve sterns, it is recommended that you check the condition of you rubber valve sterns on a regular basis. Failing to do so will result in a tire failure.

John, Useful advice on dealing with the drawer releases. However, I suggest NOT glueing the bottoms of the drawers to the sides. The drawer bottoms typically rest in a groove in the drawer frame and are purposely NOT glued to permit movement of the wood as temperature and more importantly, humidity vary.

Very impressive piece of engineering to address a complex problem. Do you have plans to produce these for sale to other OTT LEII owners? I am interested.

Oliver is using Tochta as their optional mattress supplier, replacing KTT. Apparently, KTT was having supply chain problems. We opted to have our LEII delivered in mid-February with the standard cushions. We wanted to try the cushions before deciding to upgrade to mattresses. When we were at Oliver to pickup Hull 990 we tried the Tochta mattresses in one of the showroom units. I believe Oliver is using 7 inch thick Utopia mattresses from Tochta. We decided to purchase 8" Utopia mattresses directly from Tochta. You have more choices and will save some money by purchasing directly from Tochta. Shipping is free. Also look online for coupons. We got a 5% discount using an online coupon. I recommend you see the Tochta website. I had previously been told by Oliver that they were no longer accepting direct shipments of purchases by owners without adding a surcharge.

Paul, That is very helpful information. Separately, I heard from Jason Essary, Oracle Service, who appears to recommend the same access approach (although is wasn't something Oliver Service had ever done). He mentioned the faux wall in the basement must be removed to access the wiring to the lights. I will pursue this course. Thanks, Don

I am adding a rear mounted enclosed cargo carrier to our new LEII. The cargo carrier has a 4-way male connector and integrated lights which can provide lighting functions typical of a trailer (tail lights, brake lights, directional and flashers). Although the tail lights on the LEII will be visible with the cargo carrier mounted, I would like to also have the lights on the cargo carrier function as well. I will also need to relocated the license plate mount and its light to the rear of the cargo carrier. This seems relatively straightforward, by extending the existing wiring under the spare tire cover. Has anyone added a 4-way lighting female connector and wiring harness to the rear of an LEII to provide lighting on a cargo carrier or bike rack? I have not yet removed the rear wall panel in the basement to explore for the tail light wiring on the LEII. Assuming I can locate wiring connection points, how do I route the wires out the rear of the LEII to the cargo carrier? Fishing the wires through the route taken by the license plate light wiring through the spare tire mount looks very challenging. One approach may be to route the wiring for the rear 4-way female connector into the front of the LEII where the 7-pin connector cable enters the cabin and determining connection points, which I believe would be under the front dinette seat. Then run the wiring for the rear 4-way connector under the body to the rear, fastening the wiring to frame members. I am confident this has been done before. I will appreciate hearing suggestions and lessons learned. Thanks, Don

My wife and I took delivery of LEII Hull 990 on 2/17/22. Among the options we chose was the Auto Drain, for $300. There is nothing "auto" about this drain switch, I had incorrectly assumed this switch closed the valve preventing back flow of grey water into the shower using some motion sensor to determine when the trailer was in motion. Not at all. The switch (mounted just inside the closet on the left side) flashes a red light continually when open, and no light when closed. To change state from open/close a rocker switch at the top must be held until the valve fully opens or closes. I find flashing red lights annoying, usually indicating some malfunction. I recommend avoiding this option.

@CNC, I did not see your post before submitting mine. Your description caused me to look again at the regulator, and I noticed the regulator connects to the safety valve via an adapter, one end of which is ¼" NPT and the other end is the odd size used by Champion on the two ports the safety valve. I believe you have solved my problem. I can now connect a female ¼" NPT quick connect to the safety valve by using the adapter previously used to connect the regulator. The solution is embarrassingly simple. Thanks!

@Happy Camper, I also purchased a Champion Dual Fuel 2500 watt generator, Model 200961. From reading the OTT forum I learned the regulator provided with the generator should not be used when connecting to the low pressure propane system on our LEII (pickup on Thursday). So I set about checking that I had obtained the proper low pressure hose and connectors to eliminate the Champion regulator. I tried connecting a low pressure hose with common ¼" NPT quick connectors to my generator. I then learned the male quick connector on the hose was incompatible with the female quick connector on the generator, and could not be connected. Comparing the male quick connector on the Champion regulator male quick connector (below, left) with the ¼" NPT quick connector the low pressure hose (below, right), I found they differ slightly, as can be seen in the photo below. The ¼" NPT quick connector will not connect to the female quick connector on the generator. On the left is the male connector on the Champion regulator assembly; on the right the low pressure hose and ¼" NPT quick connector I purchased on Amazon. DOZYANT 18 feet Low Pressure Propane Quick-Connect Hose, RV Quick Connect Propane Hose, Quick Disconnect Propane Hose Extension - 1/4" Safety Shutoff I contacted Champion technical support and found them to be, essentially, no help. I searched extensively online and found this link: https://www.forestriverforums.com/forums/f224/champion-dual-fuel-inverter-q-c-to-rv-on-board-propane-153043.html The photo shows a layout of various parts, with detailed notes. This looked straightforward, so I proceeded to obtain the needed parts. Only after receiving the parts and attempting assembly did I discover the ports on the safety valve are NOT ⅛" or ¼" NPT, but some ******* size no one has ever seen before. I spent most of a day calling and visiting suppliers of hose connectors for gas and hydraulic applications in the DFW area. None had any compatible adapters to connect the common ¼" quick connects to the ports of the safety valve. The connectors on the Champion hose connecting the regulator and safety valve measures 0.44" O.D., with a 12 pitch. Left- ¼" NPT connector; Right- Champion regulator hose connector Left- 1/8" NPT connector; Right- Champion regulator hose connector Having reached an impasse, I decided to purchase a Y connector and a high pressure extension hose, to run the generator directly from the propane tanks. DOZYANT Propane Splitter, Propane Tank Y Splitter Adapter with Gauge, 2 Way LP Gas Adapter Tee Connector for 20lb Propane Tank Cylinder, Work with BBQ DOZYANT 12 Feet Propane Tank Hose Extension with Gauge Replacement for Gas Grill, Heater and All Other PropaneAppliances, Acme to Male QCC/POL Fittin I don't view this as the optimal solution, as I would prefer using the low pressure connections. However, with no way to connect the Champion generator without its regulator, I have no other option. I want to be able to operate the generator at a safe distance from the trailer to avoid intake of carbon monoxide. If anyone have overcome the issues described above, I would love to hear the details.

About 8-9 years ago my wife and I were hiking/photographing for several days in Guadalupe NP. Cold and wet weather was forecast, so we planned a day at Carlsbad Caverns. The weather outside was miserable, but inside the caverns you would never know. We had a fabulous day taking photos in the caverns when there were hardly any other people there. Highly recommended. The walkways in the caverns are well developed and tight spaces can generally be avoided. I occasionally an claustrophobic, but I had no problems.

John, A new set of all season Michelins was mounted to our X5 about a year ago. We have used these tires previously and found they do well in winter conditions, not that we encounter them often. The full-time all wheel drive also makes a big difference. Thanks

John, Thanks for the warning about OTT not having de-winterized your trailer. When I received a pre-delivery prep call I was told all trailers being completed at this time of year are winterized, but they can be de-winterized for delivery or at the time of delivery. I will call OTT to verify.

Thanks to all for the helpful recommendations and quick responses. They are very consistent and in line with the conclusions I had drawn from other postings on the forum. I had been thinking of the general weather movement as predominant west to east, so a special thanks to @topgun2 for the heads up on the expected movement of the storm forecast for western NC. I had noticed the forecast for Hohenwald included high probability of snow over this coming weekend. Seeing the forecast for highs in the upper 40s temps next Tuesday and Wednesday should eliminate most of the snow from the weekend. In any case, I will pay close attention to that storm. Don

John, I should have mentioned that I do have a generator, a Champion 2500 watt dual fuel, which I plan to run only on propane. I particularly want to test the generator hookup. I also have a pair of the Mopeka tank halos. @AndrewK kindly shared with me his list of items purchased for his LEII delivery, The list has proven very useful. I will need to take my chances on availability of RV antifreeze in Hohenwald or surrounding area (or perhaps from Oliver). Our tow vehicle space will be maxed out with all the stuff for inside the trailer, generator, clothing, etc. I had feared I would need to get a small U-Haul trailer, but I believe I can avoid that. The trailer dropoff was going to be a real inconvenience.

My wife and I (RV newbies) are scheduled to take delivery of a 2022 LEII next Tuesday, January 18. Oliver Service contacted me about 10 days ago to inquire whether we wanted the trailer winterized or de-winterized at the time of delivery. I told them I preferred de-winterized, as we plan to use the trailer on our return trip to Dallas, TX. Our other alternative is to have the trailer winterized at delivery and head directly home to Dallas, with one overnight stay in a hotel. After 1 or 2 nights at Oliver to test systems, we plan travel, photography and sightseeing along the Natchez Trace Parkway, south to I-20, then west to Dallas. I have been following the 10 day weather forecasts for Hohenwald, Tupelo and Jackson, MS and they currently show nighttime lows in the mid to upper 20s F, except low 20s F in Hohenwald on Jan. 20. Temperatures shortly after sunrise will be above freezing. We plan to stay 3-4 nights at state parks, with full hookups, along the Natchez Trace. We would keep the heat on in the trailer and will have a small ceramic heater for supplemental heat. Our trailer will have the Lithium Pro option, and the optional access hatch to the basement. I also plan to install a Mopeka propane level sensing system and the antifreeze kit for the Truma water heater. Based on my reading on the forum about winter towing and camping, it is my impression traveling de-winterized for our return trip is relatively low risk if we run the furnace and open the basement access hatch at night. As a precaution against lower temperatures, I plan to purchase 3-4 gallons of RV antifreeze while in Hohenwald. I will have onboard a Viair compressor, a hand pump and basic tools, should I need to winterize enroute. I would appreciate comments and guidance from those with winter camping/towing experience. Thanks, Don

I have been reading forum postings for nearly two years and have come across a wealth of useful information. In preparation for delivery of our LEII on 1/18/22, I have often wanted to retrieve information I had previously read, or to conduct a new search on a particular topic. Searching the forum postings using the native search capabilities has proven to be very frustrating and seldom producing the desired information. My son reminded me Google's search engine can be used to search within websites. To search the Oliver Travel Trailer Forums do the following: In your preferred browser, open a new tab and enter to the web address search box: google.com In the Google search box enter the URL of the forums followed by any number of search terms: site: https://olivertraveltrailers.com/forums term1 term2 term3 Where term1, term2 and term3 are your search terms, separated by spaces.

We are scheduled to pickup our LEII on 1/18/22. Our original delivery date was 1/7/22, however, we were notified 3-4 weeks ago of the new delivery date, caused by supply issues. I received a phone call from the assistant sales manager. This change did not cause us any particular problems. Actually, I view the new date as more desirable, being on a Tuesday, rather than Friday. Should we encounter any delivery issues, I would rather not have to wait over a weekend for resolution. Also, since we have a winter delivery, I had inquired how Oliver handled delayed deliveries. If memory serves, Oliver will store your trailer for 45 days at no charge. Beyond that there is a nominal charge. Your sales person should be able to provide details. Don

Very clever design. Could you please post the dimensions of the insert box?

In preparation for delivery of our LEII in January, 2022, I have been researching many accessories I expect we will need, including generators. I have seen many recommendation of the Honda 2000/2200 watt generators and acknowledge their reputation for reliability, durability and quiet operation. I also see the appeal of running a generator on propane to avoid the hazard of hauling gasoline and maintenance issues associated with gumming in the carburetor. The dual fuel generators, such as the from 2500 watt Champion, look very appealing, especially since they cost ~$575, with no conversion kit required and a 3 year warranty. I acknowledge they are not as quiet as the Honda generators. I have read a number of favorable reviews of the Champion generators, including by Oliver owners here on the forum. However, the cost comparison is heavily in favor of the 2500 watt Champion. A Honda 2200i costs at least $1050, plus ~$270 for a propane conversion kit, for a total of about $1320, and the loss of the Honda warranty. I acknowledge the Champion does not have the long reputation of the Honda, but I could buy two of the 2500 watt Champion generators and still be ahead $170. I could also purchase two of the 2500 watt Champions AND the parallel kit be ahead approximately $100 versus the Honda 2200i + propane conversion kit. Having two of the 2500 watt Champions and the parallel kit could also provide backup for critical residential loads during power outages. I live in Dallas, TX. I expect to see MORE power outages over the next few years. Can someone provide a compelling argument why I should buy a Honda generator and a propane conversion kit?

We have ordered a 2022 LEII and were also asked if we would like an earlier delivery date. This opportunity arose in connection with the introduction of the Platinum Solar option, which we declined. We were being asked if we would consider trading delivery dates with someone ahead of us in the queue, who might want the Platinum Solar option, not available until October, 2021. One significant advantage I see in the 202 model LEII is the no-lube Dexter axles. I was told this feature would be available only on the 2022 models. Thus, I declined the possibility of an earlier delivery date, and held to our January 7, 2022 date. Avoiding the PITA of having to clean and pack wheel bearings every year seems worth the wait.

When on our factory tour on March 18, we were told Oliver has discontinued the graphics, except for the front of the trailer. We chose a color combination for the standard Oliver logo graphic. I don't know the effective date of this change, but it certainly applies to 2022 models. My understanding is the model year changes in October.

We have just ordered an LEII, and currently have 1/7/22 delivery date. I also like your mod and hope you will share construction details. I also contemplate mounting a Lagun table using the design by Overland, mounted under a bed rail.
