TPMS monitors RV tire pressure and temperature and sends updated info to wireless color monitor every 5 minutes. Flow through design lets you inflate tires without removing sensors from valve stems. Presets let you monitor up to 4 separate vehicles.

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 flow through sensors that attach to the valve stems of your tires. The flow through design lets you inflate or deflate your tires without removing the sensors. 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 38 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 it is not necessary remove the sensor. Simply unscrew the cap.
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.

We have travelled to FL from NJ and to IA, NY and back. The sensors work great. You set the pressure notification value and when the air goes below that value a beep starts. The display does a continuous scan which is easily seen if you put it on the dash. I would definitely buy this again.

The TST TPMS works okay. It saved us on one trip when a valve stem broke. Notified us of the tire going flat. The sensors along with the monitor do not give accurate readings but the readings give a good indicator how the tires are going down the highway. I also have the extender for when pulling a trailer or car.

Still working great and no need to replace batteries. I took the 4 off of the Toad for the winter, reinstalled them this spring and everything is working great. A definite must have for both the Coach and especially the Toad.

After 2 full seasons of towing, I have had absolutely No issues with these. They hook up flawlessly ever time and give me piece of mind on the longer hauls. I would recommend using this system on any rv that gets used regularly. I have seen a couple of accidents due to rv tires exploding and both were totals. A really good way to screw up a vacation.
