TST 507 Tire Pressure Monitoring System, 2 Flow Thru Sensors for Metal Valve Stems by Truck System Technologies, TPMS for Caravans, Motorhomes and campervans

They seem to work well. I would however make sure you use the security nuts that come with it. I didn’t and one of the caps worked itself loose. Lost air immediately in the tire. Once I put the security screws on we ran about 2000 miles with no issues

Was ordered to add to my Motorhome setup for my Toad. TST is great, I have two systems. One on my Truck and one on my Motorhome.

Works perfect

EZ using new 770 monitor. Worked flawlessly on our toad pulled behind our RV.

We just started using them and they are working great

Monitors are working great with original TST system. Now I can monitor my dolly and car behind my motorhome!! No worries

worked as described. Like the replaceable battery so not throwing away sensor anymore like the pressure pro system sensors. already saved a tire on my tow car

Working as advertised, shipped on time. It even came with extra gaskets.

Mounted on tow car behind motorhome. Works as described
