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

I had the old style cap mount and would have to remove them each time to air up the tires on the RV. These are so much easier. Accuracy is spot on also.

Been using these sensors for over a month now and they seem to be accurate so far so good

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!

Worked as expected, as I have master unit and they work for me.

Good product

had a different brand for years. This one out does it by a land fall. not at all sorry went to theTST

Replaced my older style flow thru sensors on my 26 ft travel trailer. Programmed all four sensors without any issues and installed each one at a time. However on my first trip the two sensors on the left side didnt provide any readout on the display inside my pickup truck on a one hour trip. The two sensors on the right side were OK, as well as the four button caps on my truck. Not sure why just the left side wheels on the trailer are displaying information.

Its a shame TST doesnt sell these in a two-pack. My boat only has two wheels, so Im paying for two extra sensors that I may never use.

Work fine.

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!
