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

I used this on My Grand Design 34 ft travel trailer. Easy to install, but need to follow instructions closely. Functioned as advertised. NO problems at all. Provided added safety reassurance on move from NE Pennsylvania to Myrtle Beach SC. Glad to have in prep for early summer trip to NW USA

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

The instruction were easy to follow. It was pretty much plug n play. Set the pressure limits on the screen. Screw on the sensors. Link the sensor to the tire position and youre done. Linking the sensors took maybe 2 minutes. It is capable of running off the internal battery so having wires plugged in is not an issue. There are 2 mounting devices; window suction cup or a dash pad. I prefer the dash pad. The display is easy to read as it cycles through easch tire position every 6 seconds. The signal booster, although not really necessary to mount was easy ro install as well. Mounting it to the exterior of the battery box as the instructions say, made installing the booster a breeze. directed

Customer service was great. I knew immediately when I started having a tire problem and was able to prevent major damage to my RV. Paid for itself on this one trip.

Two sensors infested water and heavily corroded the batteries. I was able to recover one sensor with a new battery but not the other.

Good

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.

I installed the 507 TPMS by TST on my 2016 F250 6.7L PowerStroke and 2018 Heartland Fuel 355 toy hauler. The system works great. Easy to set-up and installation was a breeze. Now when Im pulling my 16k lb toy hauler, Ill be more relaxed knowing what all my tires air pressure and temperatures are easily monitored. A must for RVers!

Displays temperature and pressure of each tire and has four alarm settings. Must have.

Was really excited to find a TPMS system that didn’t lose signal on my travel trailer and works without needing to be plugged in. I have only taken one trip but it worked well. The install was easy - just install the flow thru valve until it hisses and the sensor will be found. Install the repeater on the battery box. Set the minimum and maximum PSI on the display, charge it up and go! It’s a little costly - at over $300, it’s something I had to put a lot of thought into it and research before buying. However, I am hoping it is worth it.
