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

Tow Vehicle

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

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.

EZ using new 770 monitor. Worked flawlessly on our toad pulled behind our RV.

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.

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

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.

I have the non-flow through sensors, recently the inside dually kept loosing pressure, it was a pain to get the sensor on and off just to put in air. eventually i had to replace the valve stem that was leaking.. i bought two flow through sensors for the inside dually tires. its a good choice,.

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!

Did just like product said driving down the road noticed the pressure was dropping off slowly told off look for a nail nothing. Folding the truck stop filled up air entire took off down the road again. About three miles down the road the system let me know the air was leaking out faster than normal and alerted me before it got too low on pressure turned around put on the spare should have done that the first time
