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

Have to check battery caps and make sure they are tight when ever you stop. They are worth every penny to keep from damaging your RV or trailer. Dont leave home without them.

I like these better than the banded interior tire models that break.

Monitors are working great with original TST system. Now I can monitor my dolly and car behind my motorhome!! No worries

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.

Ease of mind when traveling with my pickup and camper

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

Centrifugal force would render these road debris in 100 miles or less. Sorry, I cannot endorse these.

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

TST has saved my tires and large motorcoach from expensive repairs and damage not to mention our safety.
