Thank you, friends for your inventive and informative responses. I can always depend on the Oliver community for THE BEST HELP! Happy Travels!

@2008RN I belive the answer is yes. See the youtube video below on how to set it up.

@HDRider Jeff: I do not think the bumper needs to be removed. On my OTT, Elite II, the trailer hitch receiver needs to be removed.

I am too. What usually gets me to actually read the instructions is I run into a brick wall. Just as you did. Then I'll post it to the forum. Just as you did. So no worries. Please do post a pick, one of us out here will figure it out. GJ

Yep, that's the way it's done by about 1500 of us. (1500 is my guess as to the number of us with 16" tires.) Some thoughts come to mind. With the downsize of the tires from 16" to 15" was the design changed for the tire removal that would cause your difficulty? If it was, if you were to reduce the pressure in the spare tire to allow a slight reduction in the diameter would that make a difference in your situtation? Was your spare tire changed to a larger size? (Not likely with a 2023 OTT. I believe that from about 2018 to the rim size change, the spares were the same tire as the 4 on the axles. But that is just an assumption.) Best of luck. GJ

I am terrible when it comes to reading instructions, especially when it seems like a simple task. I just checked the Owner's Manual. No mention of the bumper.

I'm past the picture taking. It is not the spare tire in the way. The bumper is in the way. I'll take a pic when I put it back together.

That's a new one. It certainly was designed to just lift the license plate and remove the big nut. The cover can then be removed with the spare tire still attached to Ollie. Kindly post a picture. GJ

I learned something today. You have to take the bumper off to remove the spare tire cover. I sure am glad I am home on a cool sunny day, and not on the shoulder of I40 in the rain.

I have another question related to upgrading to Lithium. My 2020 LEII came with a Xantrex Freedom XC 2000. Can the Xantrex Freedom XC 2000 be used with lithium? The 2000 watts has been sufficient for our life style although I would like extra capacity with the batteries that lithium would give.

Sounds like a great setup! You do need high pressure if you want an outdoor cooktop requiring high pressure. I thought about adding a high pressure outlet, side-by-side to the OEM LP outlet front of the Oliver, but realized we don't need a high-pressure cooktop. For our Napoleon grill, or the Weber Q many use, Blackstone grills and our fire ring that we use everyday it's a simple plumbing fix to remove the regulators from all this equipment, then use the Oliver LP plumbing as-is. Chris can cook almost anything on the fire ring. That's a good use of LP, since we run it anyway for campsite warmth! I built a steel surround for the fire ring to allow it to run well in the wind and we have a grill top for high heat and a taller tripod to simmer foods (see pic). We replaced our OEM installed Marshall Excelsior MEGR-253 in January with the suggested Fairview model that I believe OTT installed in later hulls. This regulator failed immediately! First trip out it made whistling noises. Second trip out, making noise again, it shut down in some odd way. The fire ring kept burning, but no indoor appliance would start (HWH, furnace or cooktop). Then after 20-30 minutes, we could see the fire ring burning weaker and weaker. I had to disconnect both tanks and do a sort of pressure reboot and fortunately we did get the furnace and other appliances to work for a couple days to get back home. I wasn't going get stuck again, so I re-installed our original regulator for our next trip. I had trouble finding Marshall Excelsior products online except for Amazon, so I contacted the manufacturer. They suggested an authorized reseller that would back the 5-year warranty named Tweetys from Bulverde TX: https://tweetys.com/marshall-excelsior-megr-253h-excelaflo-automatic-changeover-regulator---high-capacity.aspx I went with the Marshall Excelsior MEGR-253H model, H for high output. Their tech support explained there is nothing wrong with running the H model and it would allow for running more LP appliances simultaneously. This is a well-built regulator and the one that's been working 10 years is now my backup. I tossed out the Fairview model since warranty claims on a $50 part is not worth my time, the return shipping costs and I would not want to chance installing a replacement. On occasion having a rear connection would be helpful. OTT installed one, but why in the bumper?! I'm not going to lower the bumper, push the waste hose out of the way to use it. We only open that at the dump station! I thought of moving it so to be accessible, but so far not worth the effort. OTT should redesign this, mount it like they did the front outlet. We added a 12' LP extension hose with a Y-adapter to run the fire ring and grill.

Highs in Prescott are 65F this week. Most of the year I can be outside working. I understand the East has been hammered this year. I hope spring comes early for y'all this year! 😂 Spent the whole day getting everything straight that I noticed during our recent trip, while getting ready for our next trip to St George UT, just 4 weeks away! I corrected the battery support issue and installed our new LP regulator. I did a full inspection of the battery post. The single bolt was in place, the nut was there but loose, with only one thread showing. The two angle-irons seemed to be aligned at a good angle. The base mount has two bolts screwed horizontally and firmly into the frame. The two large upper bolts holding the battery platform were solid. The battery base is square, the door flush, and everything looked good. I decided there was no need to raise the post, since the one bolt at the bottom of the grove was were it was when installed 10 years ago. The original bolt is a 5/16" bolt 1/2" head and since the groove was wider, I added a second 3/8" #5 bolt 9/16" head. I drilled about 3/8" below the top of the groove which would allow for raising the mount if ever needed. Drilling though both angle-irons, with a sharp drill bit, drilling slowly took some patience! Then Chris held a ratchet with a double-long socket extension under the streetside bed opening, as I tightened from the rear dinette opening with my favorite DeWalt 3/8" impact! I first tightened the original bolt, with a short burst of the impact and it now has 5 threads showing. It certainly was loose, still hanging on! Then we tightened the other bolt which has thread sealant and a Nylok nut to boot. This is done now, likely no need for future maintenance! 😎

@jd1923 if I can get a weekend that's not freezing and I'm not working, I'd love to get started on that fix. I agree with everything you said.

Great post, Craig!

Hank White has made some fabulous modifications to their Oliver, including the propane setup. He’s mounted a block on the inside wall of the housing where a manifold and regulator are located. Stainless covered hoses go to each tank, eliminating the need for the OEM regulator mount on the threaded rod. Low pressure gas is sent to the two LP ports, and two full pressure lines go out; one to the Oliver’s interior and one to a high pressure port for devices that have inbuilt regulators such as a fire pit or grill. I didn’t take any photos…

I spliced a male cigarette lighter plug to my Tiretracker signal booster. When I tow, I just plug it into a 12 volt plug in the rear of my tow vehicle and temporarily attach it with a piece of adhesive velcro. One could also plug it into one of the 12 volt receptacles in the trailer. When I am finished towing I unplug it, lift it from the velcro and store it away until the next trip.

Well we had a “warm” day today so I decided to do one final upgrade that several others have previously done to their propane systems. I got the right angle fittings for the regulator connections a few weeks ago and finally decided to install them. It only takes a few minutes to do in place. The adapter fittings that come on the regulator have check valves built in, so I purchased standard 1/4” street elbows and reused the original adapters to make the connection. One little trick to make the installation easier, with the cold temps, the hose is stiff and feels like it will split if you try to reshape it into the new configuration. If you take the hoses into the kitchen and immerse the rubber part in a pan of boiling water for a minute, the hose will naturally straighten out, and while warm can easily be installed on the tanks and regulators with little tension in the process. There’s a much gentler bend in the hose when completed that should make the hoses last much longer. Before: After: Thanks to everyone who previously made this upgrade and for sharing on the forum.

Additionally you may want to consider replacing your valve stems to the metal variety as opposed to rubber. Rubber ones can fail when sensors are attached.

@Against The Wind We have been using a TST TPMS for several years. I opted to mount our TPMS relay out of the weather and UV exposure inside the main battery compartment with tiny strip velcro. It has worked flawlessly since installation. All I did was attach it to my battery terminals. Keep in mind this relay creates a very low parasitic draw on your house batteries. Not an issue in my case, as XPLOR is parked at home and always plugged into 30 amp. Have fun and mod On! Patriot 🇺🇸🇺🇸

Saw this post from another user...quite detailed. I mounted the sending unit for our system (not Tire Minder brand) on the outside of our front jack power head. You can easily pull 12V from the inside of the power head and decide if you want/need an on/off switch for the circuit. * I just leave mine on all the time...as the draw is minimal.*

For those with the Xantrex Freedom XC2000 inverter here's that same table. These XC2000 was the unit used put through 2024 with the lower tier battery configurations. Also these units don't allow running the AC off DC. (So these are configurations other than the "Platinum" or dual 320AH Lithionics)

If you’re referring to the little device that relays the sensor signals I installed mine in the front jack housing, there is power in there and room for the module. I repurposed the switch that controls the jack light so that I can turn the module power on and off.

The picture below is from the Victron Multiplus manual. The first row is for 12V systems that need heavier AWG wiring than higher voltage systems. I and other Oliver owners have the Victron 12/3000/120, which translates to 12V / 3000VA inverter output / and 120A max charge rate) inverter installed. The inverter powering a microwave using 130A, a Dometic Penguin A/C or an 1800W blow-dryer (both about 150 DC Amps) takes more battery power than anything else. The 2KW inverter requires a 250A fuse and the 4/0 AWG wiring is overkill, very safe will never overheat. It can run the microwave, borderline on the blow-dryer which is generally only run for a few minutes. Borderline/not recommended to run an A/C unit as inefficient as the Dometic model, but fine for new inverter or variable speed A/C models. Victron suggests a minimum of 400 Ah in battery capacity (many have upgraded to 600 Ah and we recently added another Epoch 300 for total 900 Ah). Not sure why they call for 2x AWG 1/0 wires (maybe smaller wires are more easily routed in boats?), but cross-sectional surface area of 2x AWG 1/0 wires is just under, basically equal to one 4/0 AWG wire. The combined length of B+ and B- wiring must be less than 5m = 16.4 FT or larger cables are needed. In our hull the two cables add up to less than 12 FT. I replaced the 250A fuse with a 400A ANL fuse as spec'd in this chart and the OEM wiring OTT installed is just fine! 😎 I made the error of having our hot water heater turned on by electric, not realizing this I turned on the Dometic, no shore power, all on the Victron MP2 inverter. It ran for 10 minutes before I realized what I had done. The Victron output was over 3400W the entire time. It's rated at 3000VA but produced 400 more (there is some technical difference between VA and W which I do not yet understand). I believe they spec the 400A fuse so it can go over spec for short periods of time. The Victron MP2 is a beast!

I just finished cleaning up after the blizzard and this is what I was looking at this morning. It's getting old. On a serious note, there was a fatal accident after the storm when someone was trying to pull out a stuck snow plow with a tow strap attached to a hitch. The hitch broke off and whipped into the cab of the truck from the tension on the tow strap. Most hitches aren't designed to handle the forces involved in a hard pull between two large vehicles. Just a reminder to be careful out there.

Hello Friends, We got a Tire Minder i10 TPMS for Christmas and after reading over the installation instructions, I feel they have catered to our neighbors who have a battery outside their rig instead of like ours where the batteries are enclosed. I’m looking for some technical advice as to where I can access a reliable power source to power my TPMS. As always, your good advice is always coveted.
