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 have 6 sensors on the motorhome placed 8/19 but I have a towed vehicle to monitor so I got four more sensors in the Spring. All 10 sensors work great rain or shine. The monitor has caught two leaks and alerted me to excess brake disc heat while towing. The rig is much safer with the TST pressure/temperature monitors and only need annual battery changing.

Very good

Mounted on tow car behind motorhome. Works as described

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.

Much larger than I expected. Easy to install and they feel secure.

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!

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

The TST system is just peace of mind for me. Have used for years, and worked well, just upgrading to the flow thru version. Noted a 1 star review that said would not last due to road damage. Well, IF you have the right valve stems (metal) that is NOT a problem, have not had one in ten years.

Just back from 1500 mile trip and these worked great on my trailer.i felt much better rolling down the road and able to keep an eye on my tire heat and pressure

Shipping was fast , install easy, set up was easy with well written directions
