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

Work fine.

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

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

Ease of mind when traveling with my pickup and camper

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.

I have the tst system but I needed 2 more pass through valve stem Monitors. They work prefect with my existing system. On time delivery product as advertised

good to have these on our tow vehicle as at a glnce we know the status of our tires! Prompt delivery.

They did their job in the first few weeks of installing them on our tow vehicle. We tow a Nissan behind our RV that picked up a nail in the back passenger tire. We lost ten pounds and were alerted of the problem before we ended up with a blowout while towing. So I highly recommend them if you are towing a vehicle behind your RV. We have pass throughs for the RV itself and love those as well.

I am satisfied with these TST tire pressure/temperature sensors. They are probably not dead accurate for either pressure or temperature but any gross outlier among your tires can be spotted and watched. After carefully filling all tires to manufacturers recommendations, the tire pressures on each axle only read from 0 to 4 psi of each other. Once driving, the pressures diverged more with tire loads, wind and sun effects . I like the immediate notification of a sudden air out condition or over temp condition.

Great price ..... works and thats what matter, piece of mind
