TST 507 Tire Pressure Monitoring System with 2 Cap Sensors and Color Display for Metal/Rubber Valve Stems by Truck System Technologies, TPMS for RVs, Campers and Trailers…

This works. First road trip out and we could have had a tire failure. The high pressure alarm sounded, we pulled over and stopped, adjusted the air pressure, and went on our way. TST customer service was very helpful in setting up the system. Use the repeater to get the best results in wireless readings.

I purchased this product to keep an eye on my trailer tires. Havent taken it out yet but will report on later!

I pull a 36 foot 5th wheel RV and get constant readings from the sensors and amplifier that give a great feeling of confidence. Ive spent years wondering how my RV tires were doing as I traveled. The TST system was easy to install and has a bright display that updates quickly...

Easy to install after getting advice about pairing sensors

Hopefully will never have to tow my trailer without this again. First trip was 700 miles. Such a great peace of mind to see real-time pressures at all times. Set up was a little tricky at first. Realized a hadn’t set alarms for each wheel. Once I figured that out with a YouTube video, all was good. Highly recommend this product for people who tow trailers.

Had a blowout on our towed vehicle behind a 36 motor home. Had no idea until a trucker pulled next to me, honked his horn, and motioned toward the rear of me. The tire was completely off the rim. Decided I needed to do something to monitor these tires so purchased TST. Put the sensors on the wheels of our vehicle which is being towed. Tested them out and was absolutely amazed at how it displays the accurate tire pressure and heat of each of my tires on the monitor located on the dash of my RV. I had a slow leak on one of the tires and when it got to 29psi, an alarm went off on the monitor. Very, very impressed. Plan to purchase more to monitor the tires on my RV. This system will monitor your RV as well as your towed vehicle.

This product does an excellent job providing trailer tire pressure and temperature monitoring for our dual axle trailer RV. We ordered the six sensor kit to allow one monitor for the spare tire and one for a backup sensor if one ever gets lost or broken. Instructions were easy to follow, had it set up and working in 25 minutes. Our setup with a pickup truck towing a 25 foot travel trailer did not even require the included booster to function flawlessly. Can already tell our travels have less worry, being able to recognize tire issues before any real problem occurs. Highly recommend!

Great product received it on time. We full-time in our motorhome and so now we have the Peace of Mind when were rolling down the road!

After hearing horror stories of tire blowouts and ultimately trailer damage - I got this for my 6 wheeled toy hauler. Worked fine - though I am not sure how accurate it was as I couldnt check it at the time. Screen was small which was ok - but now I have 3 different screens in the truck going down the road!!! lol Installation was confusing, but TST help was wonderful and walked me through it. I would recommend this without hesitation.

After suffering a major tire blow out, with extensive damage to my rig I became a big fan of TPMS. Heading to my source TechnoRV for some insights on the product I made a quick decision to purchase one. I just put new tires all around and wanted to be sure that I was monitoring the tires with better tech than a manual pressure gauge. This system did not let me down. The installation was a breeze, setting up the monitor was made easy by the very clear directions and off I went. The system paid for itself the first day of use. Seems my tire dealer installed the wrong valve stems in my new tires. They did not fit properly. A day out from a planned trip I fired up the monitor to see what my tire pressure looked like. The Alarm was singing immediately, I had a new tire going flat. I pressurized it only to find that after a few hours it was not holding air. Off to the tire dealership I head and find out that valve stems did not seat properly. Off came all 5 tires and new steel high-pressure stems were installed. Had I not discovered this prior to my trip I would of likely just manually checked the pressure, filled the tire with air and off I would have gone. A few hours later I could have had the possibility of all my tires go flat heading down a 6% grade outside of MT Eagle, TN ......not good. I could not be happier with my purchase and the support from the vendor.
