TST 507 Tire Pressure Monitoring System with 4 Flow Thru Sensors and Color Display for Metal Valve Stems by Truck System Technologies, TPMS for RVs, Campers and Trailers

Bought this after consistently seeing postings on RV websites about RV body damage caused by blowouts. Had new tires put on 2 weeks ago and installed the sensors. As we were starting our trip I noticed left rear tire was losing pressure fairly quickly. Detoured to tire dealer who discovered that rim had not been properly cleaned and new tire bead did not seat properly! Without TST this tire would have gone flat and most likely the front axle tire on my fifth wheel would have blown under the unequal load. Very satisfied customer. ***Urgent Update** 2nd half of our trip saw another leak in a different tire. Back to the dealer. They had inadvertently installed the wrong valve stems! Rubber vs. all metal. The rubber stems were chafing where they passed through the rim because of the extra weight of the sensor. Sounded bogus, but a close exam of the stems proved they were right. They replaced all 4 stems with 100% metal stems - just like the TST instructions call for - and all seems to be well. Coincidentally on our return trip home we had seen a travel trailer by the side of the road with a blow out and body panel damage! Was grateful it wasnt us.

Installed on a 28 5th wheel. First trip with sensors, it saved me twice. On the way to Yellowstone, after driving 400 miles, I noticed 1 tire had dropped 15 psi. I figured I picked up a nail in the tire. I monitored the tire and it held the pressure until I got to the camp site. Without the sensor I would not have known about the nail until I was getting ready to go home a week later. I fixed the tire at the old faithful car repair shop ($56 to fix a flat). On the way home, Im driving through Denver at 70 mph when the alarm goes off. The pressure was dropping quick, but I had time to move over 3 lanes of traffic and find a safe place to change the tire. No damage to the tire, rim or trailer. It was also nice not looking at the trailer tires in the rear-view mirrors every 5 minutes.

I bought this for my 29 travel trailer to keep a close eye on my trailer tires on long trips. The set up is easy enough as long as you follow the instructions. Once you set the parameters for the sensors the system seems to retain them well. I have not had a tire exceed any of the limitations to speak to the notifications. The only reason its not getting 5 stars is the display is terrible. unless you are driving at night it is very hard to read at a quick glance. I have followed the guidance on their website to tape over the ambient light sensor which made a minor improvement, but all in all you need to keep it shielded from any sunlight to read it clearly. Ill post pictures when I get back to the rig.

This gives me peace of mind while pulling our 5th wheel travel trailer. Were new to this camping thing, but getting into it.

Easy to use and read. I installed myself without having to call my son. The tire pressures will register without moving the trailer. You can add or release air from the tires without removing the sensors.

Great product. The suction cup holder clips broke on initial install. Contacted company and they provided a new one right away w/o charge. The monitors are easy to install/program. Definitely provides piece of mind while towing. Obviously, they won’t prevent a blowout but it will alert you of any leaks (which probably caused previous tire failures I’ve had). Having hydraulic jacks & the close proximity of the lines to the tires - I don’t want another blowout happening & tipping those apart. A little speedy, but cheaper than having hydraulic lines repaired/replaced. Thanks for sending the replacement holder. Display cycles through & is easy to see in various light conditions

I would never pull another trailer without this

Easy to use product. Gives me peace of mind when towing my rv.

Easy to install and pressure and temp readings are very accurate!

Initially hard to set up for two axle RV but once I figured it out and redid the configuration it works good. In the beginning I also thought I had a bad sensor but it eventually started getting accurate.
