Question Ram factory TPMS for trailer

I have a new Ram 3500 with the factory trailering package which includes 4 TPMSís for a trailer. I took my RV to a tire store to get the sensors installed, but the sensors donít have a lot of thread on the stem. The RV aluminum wheels (on a Sabre 5ver) are fairly thick, so there is not enough of the thread on the stem sticking out of the wheel to be able to fasten them down. Has anybody else run across this problem, and if so how did you solve it? Are there any other aftermarket sensors that would work with the Ram factory system, that might have longer threads on the stem?

It will cost more but you can get internal sensors.

The major TPMS aftermarket companies have them. I think the last set I saw was from TST. A quick google search "internal tpms for rv" found these at etrailer:

Thanks for that info, but these sensors appear to be for some aftermarket system, which I don't want. The Ram has the capability to display the trailer tire pressure on the same screen as the truck tires, using the supplied sensors. If I can find some with either longer threaded stems that work with the factory system, or if I can find a way to band the Mopar sensors I have to the center of the wheel, that's what I'd like to do.

In theory, there are tons of "universal" sensors. Even Walmart tire center has them. AFAIK, they tell the sensor what vehicle it's for, and then it does the right frequency, etc.

That said, I run OEM ones on all 12 of my snow tires. Tried one universal one once, and it didn't work. Dunno why.

Honestly, the wheels and a machine shop and a couple hundo are likely the easiest solution.

Following, I'd like this also to eliminate one more thing on the windshield.

Pressure sensors

I two would like to eliminate another monitor on my dash. I looked into the Ford pressure sensors for my trailer. I found it was cheaper to install the TST system. I have found that it gives more information and a quicker alarm alert than the factory system. I have the ones that go on the outside tire stem so I can switch to the new trailer. System gave me enough warning on a nail, I was able to pull over and change prior to any damage.
When they did a tire rotation on my Ford F-350, dealership did not adjust tire pressure in tires. This put 80 PSI on the front and 65PSI on the back. I drove 8-10 miles before any alarm sounded. Given it was not a "Major Loss of Pressure", still a long time. Maybe quicker if I actually was losing pressure, I hope so.

I have a 2019 RAM 2500 with the factory trailer package, but I don't see an option to add the trailer TPMS to the dispay, what am I missing?

On my 2020, there was a specific option for a trailer tire pressure monitoring system. It stickered for $345.

I have the same issue. The easy solution would be steel wheels.
