I installed a TST 507 system on my 5th wheel and truck back in March. The only trouble that I had was that I had to had add a repeater because my 5th wheel is almost 39' long. No problems after that. Twice on the trip I received an alarm and both time it was because of a tire problem. The system saved me from damaging the trailer tires and allowed me to pull off where it was safe. The system also made me aware of a very slow leak on one of the rear tires on my truck. Which I had fixed before it became a real problem. This is a great system and I am very happy with it. I also like the fact that I can use it without having the 5th wheel hooked up. Of course it only shows the truck tires but that is what I want when I don't have the camper hooked up.
