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

worked as described. Like the replaceable battery so not throwing away sensor anymore like the pressure pro system sensors. already saved a tire on my tow car

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

Work fine.

This is a great system, it was easy to install and program. I wish we would have bought it when we got our RV. Its not only is a sense of security knowing the the tire pressure and temperature is monitored but also before each trip we are not checking the tires the way we used to. Highly recommend the system. Also the service from the company is the best, I had a few questions on a Saturday and they were available.

Been using these sensors for over a month now and they seem to be accurate so far so good

Well worth the money ,they work very well on my trailer.

Use these on my toad. They all worked fine with my existing TST monitor. Removed the anti theft feature to make them smaller......( I remove them when in doubt....and when the trip is over). Also I dont program them in any special way as far as position....all I want is a warning if ANY tire goes low ANYWHERE on my RV + the toad............dont care which one (I plan to stop and look things over ASAP for ANY monitor warning. I have them on rubber valve stems (fairly short ones) on my Kia Soul ...... so far (2000 miles) no problems.....knock on wood.....dont want to have to install metal valve stems.

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

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.

They seem to work well. I would however make sure you use the security nuts that come with it. I didn’t and one of the caps worked itself loose. Lost air immediately in the tire. Once I put the security screws on we ran about 2000 miles with no issues
