Since this thread is fairly recent I want to share my recent experience with TST Truck Systems.
I have the TST 507 flow through TPMS System. They are currently 2 seasons old. I have another year warranty left on them. Nope, I'm not complaining :-)
For some odd reason my Receiver/Display started to randomly detect my sensors, if at all. After performing the recommended suggestions to activate the sensors thinking it was them, it turns out it's the Receiver/Display.
How do I know? Bev at TST sent me a completely new system Express so I would have a working system this weekend when DW and I depart for 3 glorious weeks of camping, FINALLY.
From the time I contacted Bev, until the new system arrived, 2 days passed. I'm in Canada!!!
Anyway, I saw this thread, Have made recommendations pertaining to TPMS systems in other threads, Specifically TST because I did my homework as well to figure out which system to go with. Bev proved all that I had read about TST and their support.
About Valve stems, Heres my post about the solution I went with. http://www.jaycoowners.com/forums/f1...tml#post362903
Note: I'm watching those rubber stems really closely and am happy to have a working TPMS again.
Now to ship back the parts I did not use, and the broken Receiver/Display.
