I had the same experience with my TST system on our previous coach. It became such a headache that I gave them all away. I could never get the repeater antenna to work on our toad (I was in contact with the manufacturer and they replaced a couple of sensors).
I never used my air compressor more than when I had my TST sensors. Now, my TST system was probably an early model but a pain in the butt nonetheless.
After several frustrating months, I removed the sensors and just checked my tires manually before every departure and that worked great for 5 or 6 yrs. Never any failures. And, I know that I could have run over a nail the minute I left a campground. What a waste of the $599 I spent on those darn sensors.
Our new coach has the built-in system and seems to work fine so far. I will never attach anything to my air stems again. The built-in systems on several cars that I have work fine. Even the Honda has a TPMS built-in and warned me once of a low tire due to picking up a screw. I had to have the tire patched.
And that is almost exactly the same experience I had. I couldn't agree more with you.
