I wanted something that worked all of the time so when I had my sensors stopped reporting properly with my TST system, I just chucked it and went with another brand. I didn't really think I should have to accept that anything in my coach was interfering with the TPMS sytem. I figured that was the manufacturer's responsibility.
I bought the EEZ RV TPMS system four years ago and it has worked great and is obviously compatible with everything else in my coach. I changed batteries at two years, just because they are cheap and easy to change so I don't know how the system reacts to a low battery in a sensor.
My EEZ locks on to the wheel sensors in a few minutes and always before I have gotten out of the RV park and on to the highway.
Since I have the flow through sensors, I still check my tire pressure before starting out each day. The flow through sensors means that my sensors stay locked on to my valve stems and checking tire pressure is a simple as removing the cap and using my tire gauge. Since we usually travel during the Winter months, we are used to a large swing in the temperature so it is not unusual for me to have to add air when we start out on very cold morning.
