TPMS monitors your RV's tire pressure and temperature and sends real-time info to a wireless color monitor. Tire sensors run checks every 12 seconds and send alerts to monitor. Presets let you monitor up to 4 separate vehicles or orientations.

Specs:
This TST tire pressure monitoring system monitors the pressure and temperature level of the tires on your RV, motorhome, 5th wheel, motor coach, or trailer. The system utilizes sensors that attach to the valve stems of your tires. When a tire sensor detects an anomaly, it will wirelessly transmit an alert to the included digital color monitor. Your monitor will emit flashing lights and an audible alert to notify you of an issue, and it will display details regarding the anomaly. A booster is included to strengthen and amplify the signal that the sensors are sending to the display monitor.
Initial Setup
The TST TPMS is easy to set up and includes all mounting hardware and tools for installation. First, assign the tire sensor positions through the monitor's Learning Mode. Label each sensor with the corresponding numbering code sticker so that you know which sensor is programmed to which tire position. When you are setting up the sensors make sure the one you are programming is at least 2' away from the other sensors. Otherwise the other sensors will interfere with the sensor you are attempting to program. Once the tire sensors have been recognized by the monitor, attach them to the valve stems of your vehicle's tires. Next, install the booster and connect it to a 12-volt power source on your vehicle or trailer.
Use the included suction cup holder to mount the color monitor on your windshield so you can monitor your tires while you drive. You can also use the included rubber, non-slip cradle mount to set the monitor on your dashboard.

Multiple Wheel Layouts
You can program multiple layouts into the monitor, and you can scroll through each setup on the screen. This system can support up to 4 tire layouts and up to 115 tires total. Make sure to set your high and low pressure alarms for each layout that you are using. Some examples of popular layouts are shown above.
Tire Sensor Installation
Note: To inflate or deflate a tire you must remove the sensor.
Booster
The booster - or repeater - amplifies the signal strength that the sensors send to the monitor. Booster installation requires a 12-volt power source. It is waterproof and can be mounted inside or outside your vehicle with the included mounting hardware. On a trailer, you can mount it in the battery box in front of the propane bottles. On a 5th wheel, you can install it in the house battery bay underneath the overhang. You will want to place it below the bank of mirrors so they don't bounce the signal back and cause the system to malfunction. On coaches with towed vehicles, you can install it in the back battery bay. The power draw is so minimal that you can leave the booster installed without running the battery down. If you decide to unhook it for storage remember to reconnect when you are ready to hit the road. A red light on the repeater indicates that the unit is connected to power and operating correctly. Repeater installation is required for warranty compliance.

Would not travel without a TPMS system. We were southbound through Atlanta during a workweek pulling our 30’ TT, wife was driving, and suddenly the TPMS alarm went off. Rapid loss of pressure in one of the tires. We quickly found an off ramp and a safe place to change the tire and with the help of our tire changing ramp, we had the tire changed and was on our way in no time.

This TPMS system is still working great, and I havent even had to replace the batteries in the cap sensors yet. I decided to recharge the battery in the control unit for an upcoming trip, so I took the control unit upstairs in our house and plugged it into a 12 volt power supply. A short time later when I checked on it I was amazed to see that it was displaying the outputs from 3 of the cap sensors on the trailer thats parked out in our back yard! Without a doubt this is a system that I strongly recommend to anyone who owns a travel trailer.

Update 2nd yr: sensors the ones without user replaceable batteries are still good. I might try regular sensors next time, they all have same waterproof rating. Next time I might be interested in a different brand system altogether with better screen visibility, screen durability, and price.

I stand by my original comments of a year ago. Still a great product and they have worked as advertised. We have had two tire related problems that the pressuretemperature monitors detected before there was a problem. Highly recommend.

Still working flawlessly after one year and we have been using our travel trailer a lot.

Follow up after a year. The TST system has protected us over 5000 miles. Head unit easily finds the sensors, and we get great piece of mind knowing where were at with pressure and temps. The system even caught a slow leak long before it could have turned into a mess. We have a 25 ft Airstream, so a tire blowout could be very damaging. Changed batteries on the sensors when we got our RV out of storage last week- thats the only maintenance weve had to do. Highly recommend the TST TPMS.

The product continues to work great and give me piece of mind on our RV trips. As a precaution, I installed new batteries in the sensors for the 2022 RVing campaign.

After 1 year, the TST system has been working perfectly and already saved us from a catastrophic tire failure.
