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

Purchased to replace lost sensor. These newer sensors appear to be improved somewhat and work with the 507 receiving unit which is now 5 years old. Would easily recommend.

We drive a 38 Class A motorhome and have had the TST TPMS sensors on all 6 tires for over a year. So when we added a Honda CRV as a tow car we needed these additional sensors for it. These are easy to program and give a very strong signal so we didnt need to use the repeater to get signal to the RV driver. In my opinion having a TPMS is a must have item for any RV motorhome and tow car and weve been very happy with the TST 507 model.

Easy to add the sensors to your system. I have a 31 Class A RV and two a Jeep. I did not install the range extender. Works great without it!

This is the upgrade design. No tools to swap out the batteries. Still seems to be plenty strong

Easy to add to the main system unit. Gives good feedback on status of tires on towed vehicle.

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

good stuff

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

Excellent TPMS. A bit complicated to set up, but quite doable with the instructions. Be sure to use the correct valve stems for wheel senders. Nice seeing in real time 10 tire pressures. TST offers the best customer service!

I tow an expedition behind my Mountain Aire- they work great! I am within 1# of my digital gage. I didn’t put on security nuts. I remove when I unhook. Then check and air up before we start to tow again. I have a repeater on RV
