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

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

The product would have been good if it was not old stock with flat batteries, batteries are only good for a year from when they were made - so $20 later out of my pocket they work. This dealer has to know that and yet was greedy and did not price accordingly! Gives in line shopping a bad name

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

Same price as everywhere else. Work great. New design.

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.

This is not a recommendation for this manufacturer. I have only had their monitor for a few months and it seems to work fine. It is a recommendation for the product. I have had tire pressure monitors for over 10 years and they have alerted me to serious tire problems several time which potentially averted major tire failures while driving. Blow outs can not only cause major accidents, but the shredded tires can cause thousands of dollars of damage to your coach, even if there is no accident. Ask any coach manufacturer what it costs to repair damage to compartments and side walls of coaches after a blow out.

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

Work fine.

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

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