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…

Would have given higher grade, but have issues with the product. Tried to setup outdoors and could barely see any characters on the screen. Had to do setup at night. Also I have a 36ft rv and shortbed truck and the sensors would not sync up without using the repeater. Even with the repeater it takes quite awhile for the sensors to sync up with the monitor.

We bought the six tire version to replace our Tire-Safeguard system that we have had for the past 8 years. The new TST barely works as well as the old one we had. We were hoping for better technology. We have a 40 foot Class A motorhome and have placed the repeater antenna as directed in the instructions. We have also removed batteries from both of our wireless thermometers as instructed. We still have difficulty keeping all six readings active. The front two tires always come in but the rear four tires rarely all read at the same time while under way. We wait until all six tires readings are active before heading out for the day but have yet to have all 4 of the rear reads to stay active during a 300 mile travel day. I waited two months before writing this review but we have traveled over 2000 miles since putting these sensors on and have been disappointed. That said as the title reads, it is still better than nothing. I am hoping that the sensor will reactive if we have major tire failure. It is good enough that, we may still buy an additional four sensors for our toad vehicle.

I received my unit today with 8 cap sensors. I dont have my RV yet, as im waiting for the snow to melt up here in Vermont to pick it up from winter storage. I was able to quickly set the default settings and the high/low air pressure for each axle. The sensors themselves paired very easily (have a non black sharpie on hand to mark them). The cap sensors installed on my truck in seconds and locked on fine with the hex nut. Not sure it will deter many people, but i used them. The unit synced up with the sensors in about 90 seconds. Three of them within 30 seconds, the last one took about another minute. I appreciate the many different mounting options/solutions, that is nice. I dont know what ill need the repeater. My rig is 30, but I received feedback in another forum that they work well without it. Guess ill find out in another 6 weeks, but am very happy so far.

Screen can be difficult to read in sunlight

This is a great system, watched instruction on how to set up on YouTube . I have a 45 foot coach and pull a Jeep so far after 2500 miles all good. This system is more expensive than others I check out but I feel better having the security it provides.

So I got my system a few days ago, 10 sensors and color monitor with a repeater. I went to TST Truck YouTube channel and viewed all of the instructional videos. That was so much easier than trying to read the instructions. Once I learned how the programming was a breeze. The installation was fairly easy also. The video on installing the repeater showed an older version with the power connection wires having nothing on the ends. They now come with circular wire connections attached to the ends. While you would think that would make it simpler it did not. Attaching the repeater to the Class A house battery directly would cause a vampire drain when not in use and undoing the battery nut to remove one connector each time would be a pain. My solution was to attach the Neg wire using the battery nut. I then cut off the circular connector on the positive wire and attached a battery clip. Now while in use I just attach the battery clip and remove it when not in use. It would be nice if TST could add a power switch on the unit to prevent battery drain and make installation more permanent. Other than that so far so good. Due to Covid I am unable to get out and test that system on the road so once I am able I will update my review. One thing for those thinking about what system to get, understand that a tire blowout can be disastrous to your RV and/or towed vehicle so do not look for a bargain, look for quality and I believe TST provides that quality.

Works great so far. We take a couple of trips a year with a 9,000 lb. travel trailer. Should have bought a system like this years ago but not sure a product of this high quality has been available for very long. Works great so far.

A little complicated to set up the computer, but we figured it out! It can control multiple trailers. Constant readings for air pressure and temperature on all tires. Super easy to use.

Used it for our Class A motor home to monitor tires.

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.
