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

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!

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

You need to read the reviews on the TST 507 TPMS system these do not work without the monitor

Tow Vehicle

I bought the cap tire pressure sensors for my trailer, to use with a complete TST 507 system I bought for my truck. They worked well on a 3-week trip except that, twice, a sensor on the trailer (different sensor each time) suddenly set off an overtemp alarm - abruptly reading over 300 degrees F. This was most disconcerting, and the first one caused me to make an emergency stop on an 80 mph freeway (I was doing 65) to check my tires with an infrared thermometer. Turned out both times to be a false alarm. I ended up not stopping for the second one - just reset the monitor. A couple of other times the monitor lost the trailer sensors. Again, switching it off and on reset the system. Two possible contributing factors: glitches seemed to happen during high ambient temperatures - above 90 F. I didnt install the signal repeater (for the trailer) that came with the system, because the system seemed to work fine without it.

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.

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!

TST has saved my tires and large motorcoach from expensive repairs and damage not to mention our safety.

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

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