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

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

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

Mounted on tow car behind motorhome. Works as described

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

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

Very good

Much larger than I expected. Easy to install and they feel secure.

Shipping was fast , install easy, set up was easy with well written directions

I had the old style cap mount and would have to remove them each time to air up the tires on the RV. These are so much easier. Accuracy is spot on also.
