I have the TST
Tire Monitor System system on my Class C and also added to my Cadillac towed vehicle. Even though the Cadillac comes with its own tire monitor system, I can't see what that system is doing when being towed behind my MH. I had to purchase a different set of valve stems that would allow me acces to the inner dual tires that would let the sensors fit on the MH. Discount Tire installed those stems, but now before I pull out of a campsite I can tell what each tire is doing, reading pressures and tempretures from the drivers seat. Well worth the piece of mind knowing I can monitor all those tires while underway and the system will alert me should it find something going on that might cause a tire failure.
