Ron, Thanks for the post. It is a good reminder for all of us (especially single axle Elite owners) to use a TPMS system to monitor the pressure of our tires. Question: Did you have a metal valve stem? The centrifugal forces exerted on the valve stems by the mass of the monitor can result in over stressing a rubber valve stem, so metal stems are preferred with TPMS. So glad your system alerted you to the loss of pressure in time for you to safely get off the road. Pete

Honestly, you cannot have enough pressure, meaning load carrying capacity in a second axle/tire to cover the GTWR load upon tire failure (unless you want 80 PSI, the reason why legal depts of RV manufactures suggest this crazy number on your trailer sticker). Either you have muscle memory from 30-40 years or more driving old trucks and towing dozens of cargo and flatbed trailers, or you need to rely on a TPMS (check it often). Yes, redundancy is one of the key factors in mitigating risk. For this reason, the idea of an Elite I (a single axle trailer) is not for me. Having owned horse trailers, farm stock trailers, car haulers, cargo and flatbed trailers, certainly a dozen trailers over a lifetime, and by my choice they are ALL dual-axle trailers. I've had blowouts on desert roads at 70 MPH. The tire tread rips the fender off a car-hauler. I realize it in milliseconds and (btw don't hit the brakes) coast nicely to the shoulder. Run you tire pressure per the load charts and add 5 PSI for a safety of margin. Additional PSI will cause your belongings to suffer, cause your leaf springs to failure (see the threads here) and just more bad stuff! Trust me (and many others here with considerable lifetime experience).

Nice. I have some Mopeka's coming tomorrow as well for the propane tanks. They also play nice with the Victron system, excited to have most everything going through the Victron VRM. Always switching between apps to monitor things. Still have a separate app for TPMS, LevelMate Pro, EasyTouch RV thermostat, and my Grilla Grill. Ha! A lot of batteries to change but no more gateways to deal with or use up energy. Do you find the Mopeka propane sensors accurate?

Can anyone tell what breand of metal valve stems work well on our rims (2021 Elite II). I purchased a TST TPMS system and want to use metal stems. Had a local dealer install the metal stems. The TPMS sensors have been on three days. Today when checking the tires to see if the tpms read the same as my guage, one tire was a few pounds low. I removed the sensor, added air, then when I screwed the sensor back on there was a distinct air leak. Yjought it was the core, but it seems air is leaking where the stem meets the rim. must be a bad seal. So my thought is our rims may need a particular brand of stems? Monday moring i'll be on the phone with delaer.

This is a LOCKED thread. I wanted to put all my links in one spot so that they are easy for folks to find. Search remains a real problem with this forum! This thread does not allow comments. If you have questions, find a dead link or just want to talk, you can comment on the appropriate thread, or start a new thread or just Message me. I will add to this page as I start new threads, so hopefully it will continue to be a good up-to-date reference. NEWEST POSTS ARE AT THE TOP. I am not going to bother to alphabetize them, LOL. I put a link to this page in my signature, so you can get here directly from any of my comments.

We've never owned a truck or a trailer. My wife and I are retiring in 6 months and diving in with all 4 feet. Tell me what we don't know please. We looked at lots of trailers and are finally pulling the trigger on the LEII. I've read a bunch of threads on here over the last year. Very helpful. But if you can point me to some that have already discussed this sort of thing, I'd appreciate that, too. We prefer simple: Everything we need, but nothing we don't. So.... LEII - starting the ordering process today 🙂. Scheduling factory tour soon. Standard except as follows: Twin Bed Floor Plan Two Upgraded Foam Mattresses Hypervent for Twin Bed Floor Plan Front & Rear Propane Quick Connects Backup Camera with 4.3” display Aluminum Storage Basket Inside Basement Access Door Auto Drain (push button drain valve) - What is this? Door lock (do I need the electric one?) TV - bought yesterday 🙂 Ram 1500 Laramie, 5.7L 8 cyl hemi, 4wd, max tow, air shocks, class iv hitch, 9 pin connector, rear video Approx 1,700 load capacity Locking hard tonneau cover, bed liner Miscellaneous side purchases (yet to be made) Generator that runs on propane - to be carried in Ollie's storage basket Surge protector (no idea what sort of electrical equipment I need for generator or shore power) TPMS for trailer Screen house carpet for under awning hoses, leveling blocks, antitheft? tools? Storage - We intend to use these toys a lot. Maybe even 6 months a year. But, inevitably, they will get placed in storage when not in use. We live in a FL subdivision, with no garage space for this size stuff. So, I thinking I buy a cover for both.

New tires after 6 years with the Michelins. They performed well just had some very small cracks starting to form on the side wall. Changed the TPMS batteries while I was at it.

Hey, John; The D52's use a massive "bearing pack" which is a sealed unit touted to be "good" for 100k miles. We'll see, for sure. Even though they're called "Nev-R-Lubes", owners still need to inspect the sealed bearing packs at 12k-mile/12-month intervals (whichever occurs first). With our current OTT camping schedule for the rest of this year, we'll likely be digging into the new 52's in NOV prior to our "winter mode." We'll report the details of the process afterwards for those interested. JFTR: We've chosen to run the Cooper Discoverers at 45psi cold. The TPMS shows a consistent warm-up (obviously not including the spare) to 52 - 53psi per tire after about 20 minutes of towing. This pressure seems to be our "sweet spot" for the loads we've been carrying for summer travel. We also replaced the curtain clips with new ones before the axle swap because we were discovering random curtains falling down after normal towing conditions. We haven't had one fall down since replacing the clips, FYI. @Patriot - good call posting the Dexter inspection procedure, thanks brother! Cheers!

A short follow up: I dropped off my (spare) tire/wheel today just to be sure that my local DCT had the metal stem I needed in stock. I have an appt Wednesday morning to have all 4 tires rotated, balanced and the remaining 4 new metal stems installed. They just could not squeeze me in today. Not a big deal, and fair enough as they were pretty slammed. They were kind enough to at least get my spare swapped out. No charge of course. I returned home, remounted the spare on the back of XPLOR. This precludes me having to remove the bike rack etc at DCT this Wednesday when I get the rest of the wheels done. This metal stem seems to be a bit lower profile or shorter than the OEM rubber stems which suits me fine. I am thinking it will keep the TST TPMS cap TPMS transmitter a little closer to the inside of the wheel away from road rockets. I am really liking the Cooper tires and as they appear to be wearing really well. I will replace them with a new this set next year. Very happy to have 16” rims as well. Cheers! Roll On!!

I thought that I'd post this in case anyone else runs into the situation that I did whereby the TPM sensor battery compartment was unable to be removed with the supplied stamped sheet metal wrench. In my case the battery compartment was so stuck on that the supplied wrench began rounding off the plastic hex nut profile of the sensor, had I gone any further the sensor would have been ruined. I ended up using a 1/2 inch six-sided socket that provided much more surface area contact than the wrench and the socket did not mar the surface of the plastic nut; even doing that I was unable to grasp the barrel end of the sensor with enough force using my hand to unscrew the barrel from the sensor until I squeezed the barrel between the padded hand grips of my channel-lock pliers ( don't use the jaw end or you'll risk crushing the barrel ). Curiously ProSmart used to ship a tool that more accurately fit the profile of the sensor but have included only the stamped sheet metal wrench in the current kits which provides significantly less surface area contact leading to the possibility of destroying the plastic nut profile. Also, when replacing tires I'd recommend changing the tire stems to metal versions rather than rubber to prevent premature failure of the stem as a result of the added weight of the TPM sensors.

I was initially very interested in the ford wired backup camera, but was very hesitant bc I had to be hardwired to the trailer. Seemed like a lot of hassle for very little benefit. I currently have an after market tpms and the Oliver factory installed backup trailer camera. The monitor is a little small and it sure would be nice to have the backup camera on the trailer display on the truck head unit, but I am very happy with what I have. I find I only really use the backup camera for a few minutes when I back into a campsite or storage for our Oliver. The wired ford backup camera and tpms seems like a long run for a short slide! Just my humble opinion.

Shortly after arriving home from our delivery trip to Hohenwald, I installed a TireMinder i10 Tire Pressure Management System (TPMS), with six sensors, a monitor and a signal booster (installed later). Four of the sensors were fitted to the valve stems of the four trailer wheels on the ground, one on the trailer spare and one to the tow vehicle spare. The sensors transmit tire pressure and tire temperature status continuously to the small monitor in the tow vehicle. The 433 MHz RF signal booster is to ensure the signals from the sensors reach the monitor. The TPMS is quite configurable and can support up to 10 sensors simultaneously. Thresholds can be user specified and the system is preconfigured to create alerts for slow leaks or catastrophic loss of tire pressure. I first mounted the sensors to all the six wheels. The sensors appeared to have no problem communicating with the monitor in the tow vehicle. I deferred about a month installing the signal booster. Mounting the sensors is quite straightforward, requiring only insertion of provided disc batteries to the sensors, then screwing the sensors onto the valve stems. I like the inclusion of a lock nut to secure the sensors to the valve stems, using a provided small wrench. TireMinder Air Pressure & Temperature Sensor TireMinder i10 Monitor On each spare wheel I added 36" long extension hoses ($11 each) and 90 degree valve stem extensions ($7/pair), based on a recommendation from @John E Davies. The TireMinder sensors are mounted to the end of the extension hoses, which are routed through the wheel spokes to the accessible side of the spares. The valve stem extensions allow the hoses to be attached to the valve stems with no danger of kinking. These accessories eliminate a huge PITA- both spares are stored with their valve stems inaccessible. The trailer spare mounts with the valve stem facing the rear wall of the trailer. The tow vehicle spare is stowed valve stem down in a well under the cargo area at the rear of the vehicle. Now the TPMS reports the tire pressure with no hassle. Even if the spares require addition of air, the access is easy, without removing the spares from their storage positions. I always intended to install the signal booster, but had not settled on the best location. The installation instructions recommend locating the signal booster on the undercarriage, toward the front of travel trailers, with the antennas pointed toward the ground. The signal booster requires 12 volts DC for operation. I searched the OTTO forum seeking information on locations chosen by Oliver LEII owners for mounting such signal boosters. I found references to mounting signal boosters within the doghouse or in one of the upper storage compartments, neither of which appeared to offer ease of connection to a 12 VDC supply. Other owners indicated they had not installed the signal booster, since the monitor seemed to reliably provide tire pressure and temperature information. While vacuuming fiberglass dust from all areas accessible under the interior access hatches, I found what appeared to be an ideal location for the TPMS signal booster. The hatch under the rear dinette seat is the location of the Progressive Industries Surge Protector, mounted to the wall on the aisle side of the compartment. Adjacent to that location is a large area of unobstructed wall. Just below the surge protector is a ground bus and on the forward wall is the rear of the DC distribution panel. I believe this is a very desirable location for the signal booster. It is located low, slightly forward of the axles, in a protected space near the needed power supply. TPMS Signal Booster Location The TireMinder Signal Booster is attached to the fiberglass wall using an Industrial Velcro Coin, which enables easy removal. TPMS 12 VDC Power Switch I chose the top of the Progress Industries Surge Protector to mount a switch to turn the 12 VDC power supply to the TireMinder Signal Booster ON/OFF. The signal booster has a green light to indicate the power is ON. The wires from the signal booster are very thin and are both black (despite the instruction manual indicating one to be red and the other black). I don't believe it matters which is +12 VDC and which is Ground (GND). I routed the wires along cables in the compartment. The pink zip ties appearing in the photos provide clues to the routing. I arbitrarily selected a position on the Ground Bus to mount one of the wires to be Ground. The other wire was routed to the rear of the DC Distribution Panel, mounted on the forward wall of the compartment. Fuse position 14 was unused, so I selected it and connected the second wire from the TireMinder Signal Booster, using a crimp-on connector. Finally, I inserted a 3 amp fuse to the front side of the DC Distribution Panel, position 14. DC Ground Bus DC Distribution Panel (Rear) DC Distribution Panel (Front) Summary Although I had encountered no problems with the communication between the tire pressure/temperature sensors and the TireMinder Monitor, I believe having the signal booster installed reduces the risk of loss of communication between the sensors and the monitor. I have been leaving the signal booster on while traveling and turning power OFF when in storage. The signal booster draws only 75mA (Transmitting) to 14mA (Inactive). I tested the range with the signal booster installed and powered ON. I was able to walk over 300 feet from the trailer with the monitor receiving signals. I have been impressed with the TireMinder TPMS system. I have not mounted the monitor in the tow vehicle, but keep it on the center console, where I can view it as desired, and also hear any alarms which may occur. I purchased the TireMinder i10 and six sensors from TechnoRV (https://www.technorv.com/) for $279.65 (no shipping and no sales tax).

That's interesting. I'm running a 2018 EEZTire TPMS as well. I purchased six sensors plus a spare so i could monitor Ollie and 2 spare tires. I'll go find my info and advise why I pulled them off my spare tires. Will be good to know for sure. More to follow.... GJ

I have the EEZTire TPMS and both the spare tire on the Ollie and on my F-150 DO register with this system for both pressure and temperature. Bill

@Ron and Phyllis the odds were against you, but with your TPMS alarm and your cool head in finding a good place to park, you really made the best of a bad situation. Good lesson you shared and we're glad to know you two are fine. 😂 Thinking back to the half dozen trailers I've owned, never going with a single axle. Needed a trailer for our dirt bikes years ago and looked hard and found a used 12 FT flatbed dual axle. Dual axles generally come on 14 FT trailers and longer, most are 16 FT. I've had blowouts on dual-axle trailers where you lose a fender but all else is good. Thanks @topgun2 for the Dewalt compressor link. I need to get one of these when we resume spending on the Oliver (need a long break). We are a Dewalt tool family, having 8-9 20V batteries between my son and us. I bring a Dewalt handheld leaf blower to blow dirt road dust off the Oliver and clean the camping mat. My son got me this for Christmas: Amazon.com: DEWALT 20V MAX* XR Leaf Blower, Cordless, Handheld, 125-MPH, 450-CFM, Tool Only (DCBL722B) : Patio, Lawn & Garden And you gotta have 1-2 of these for the campsite, or to change that tire at night if need be. I got everybody in the family one, so they would not take mine anymore: DEWALT 20V MAX LED Work Light, 100 Degree Pivoting Head, Up to 1000 Lumens of Brightness, Cordless (DCL050) - Amazon.com

@Ron and PhyllisFirst glad that it all worked out safely for you. And it’s always a good idea to check your spare periodically for correct air pressure IF you don’t use a TPMS sensor on the spare. As a part of our go to gear we always carry a floor jack, a tire temporary plug kit and we also have a portable compressor on board. (link) Not an advocate of running a plugged tire, but it will at least get you to a repair shop in a pinch. Safe Travels and hope to see you at the rally! https://www.amazon.com/40047-400P-RV-Automatic-Portable-Compressor/dp/B004B68XGC/ref=sr_1_4?crid=2CXF2TAPW4C19&dib=eyJ2IjoiMSJ9.Eys-V0OIft8RXPo9KyhLYMtEzTC1gVkd12IQ8QX0XsWgXT4wr-aQ3UNywG3dZFL50DToSh3Wv0fob50yoNsmRcRcgHxwz-S78KIlhwHb4OurfKZ4F-OX6GE_l_t2Ba2Wm9JIf2X1wjtHcrSxXsdwRvI16QVHnK_hFafbhZh2ZL1BsmgAMTdvek0kOlCLCHBwPe_wNBjfFxmqyyLDMtbvJSqrRbyR2UA2dkC8wSKrKlA.YXfRIKzFhg2jMU9BN2Pr1w-HMX_z-NSR68nn8Ji7Nuk&dib_tag=se&keywords=rv+air+compressor&qid=1714030907&sprefix=Rv+air+%2Caps%2C118&sr=8-4

For a little bit further clarification: I called and spoke with Customer Service rep Maria at the TST Office in Cumming, Ga. (770) 889-9102. I asked her if rubber valve stems can be used with the 507 TPMS bottle cap style sensors? She said yes. She went on to say, that an application requiring flow through sensors, it would require metal valve stems. To their knowledge nothing has changed in the install instructions with regard to use of rubber stems with the bottle cap signal sender. Safe Travels!

Just to be fair: I too have metal stems and have never had a problem. However, I never had a problem with rubber stems either. I think that metal stems usually make sense for those of us that have stem mounted TPMS primarily due to the reason John mentions above. But, if you tend to take your Ollie into really "wild" places where the stems are likely to be hit with rocks, deep ruts, brush, etc. then the rubber stems can be a bit more "forgiving" than the metal stems. Bill

Metal stems and TST TPMS since 2007. No issues so far.

@Ronbrink All good points especially since TST has now revised their recommendation of metal stems vs rubber. Based on this I will reconsider not using the rubber stems and replace with metal sooner than later. I think it’s also important to not over tighten the TST TPMS cap when installing it. This could break the seal and cause a slow leak on either metal or rubber stems. It’s worthy noting that the metal stems still use a rubber seal which is still subject to leaking and failure.

Greetings! I need to remove the TPMS transmitters to inflate the tires but I can't get them off. The little wrench they supplied does not do the trick. Any other suggestions? Carl

We decided to go with metal valve stems 3 years ago. Shortly after doing so we had a flat, and the metal stem had failed.😣 I took XPLOR Hull #634 to our local discount tire shop and had all new rubber stems installed and all tires rotated and balanced. Zero issues since. We use the TST TPMS system and are very happy with it. The tech who does tires all day long said he sees more failures with metal stems than rubber. That was good enough advice for me. Cheers and Safe Travels!

I just installed the TireMinder i10 on my 2022 Oliver which was straightforward enough; however now two of four tires have leaking (stuck) stem valves! I managed to screw all the transmitters on so the leaks are stopped and the tire pressure is at the planned 55 psi. Questions: Is this a common problem/result of installing this product? I assume I need to install (learn how to) some new valve stems and not some how fix? Any recommendations on brand or model for new stems? Install method advise? I have Cooper Tires "Discover HT3" tires as equipped by the factory. Thanks for any advise.

A friend with 2021 Ford f150 is ordering an Elite. Can anyone tell me if Ford supplied tpms and backup camera is available to work woth Ford screen?

Part of Annual Maintenance is to Check Tire PSI. We have TPMS on our tires. At last year's Maintenance service, per the invoice the PSI was not checked due to our TPMS. The TPMS keeps track of PSI. We can remove the TPMS upon arrival at the service center. If you remove your TPMS, how do you keep track of each sensor to its tire. What do people do? I know many have TPMS. I would like Oliver to be able to check the PSI as we believe one tire may be low. Maybe I am being overly concerned about something of little consequence. ty
