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

Ive owned several different TPMS systems on three different RVs and TST is about the best Ive found.

Product was delivered on time and as advertised. It was easy to install, and does the job it is designed to do.

Package arrived as promised. Package not sealed and did not include user manual. 4 Sensors, two tools and one little plastic package with tiny screws, o ring seals.

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!

Good product

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.

Centrifugal force would render these road debris in 100 miles or less. Sorry, I cannot endorse these.

I lost them before I had a chance to put them on .

Work fine.

Was able to set it up on my 2012 Honda CRV.
