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

I bought this for my utility trailer as an add-on to the TST 507 system that I use with our 5th wheel. These paired up with my existing receiver without any issue. Even good quality tires that are within their capacity ratings and expected life span can fail, and my TPMS has alerted me twice so far when a tire was starting to come apart at 65 mph. The warnings came in time to get safely off the road before either tire failed completely.

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

Mounted on tow car behind motorhome. Works as described

I lost them before I had a chance to put them on .

I have the non-flow through sensors, recently the inside dually kept loosing pressure, it was a pain to get the sensor on and off just to put in air. eventually i had to replace the valve stem that was leaking.. i bought two flow through sensors for the inside dually tires. its a good choice,.

We drive a 38 Class A motorhome and have had the TST TPMS sensors on all 6 tires for over a year. So when we added a Honda CRV as a tow car we needed these additional sensors for it. These are easy to program and give a very strong signal so we didnt need to use the repeater to get signal to the RV driver. In my opinion having a TPMS is a must have item for any RV motorhome and tow car and weve been very happy with the TST 507 model.

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

I already have the flow through sensors on my RV trailer and needed them for my truck. They do a great job. Its just harder when you need to add air as the sensors must be taken off to add air to the tires.

Quality product.

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.
