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

these keep you in constant touch with your tires. could really save the day if something started going wrong while out on the road

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

This is the upgrade design. No tools to swap out the batteries. Still seems to be plenty strong

Didnt need to use the extender to get signal from the toad vehicle for these.

Added to current system with six sensors Love security of monitoring all tires on RV and tow vehicle

We just started using them and they are working great

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

Quality

great add on for my existing TST system to add another trailer

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