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.

Ratings & Reviews
I did not like the TPMS. The display was too distractive. Driving the RV needs full attention but the TPMS created unnecessary distractions, usually about insignificant info.
Also, the wheel sensors are too heavy, which caused the valve stem on one the wheels to break off.
I have removed the system from my RV.
1st, questioned etrailer as to whether or not I could use this TPMS on my RV with braided valve extensions and they said yes. Prompt response, ordering and shipping as usual. I installed the system yesterday without much fuss. One fuss was due to my not following the exact sequence to program the sensors. The other was the front wheel beauty not having enough room for the sensor to pass through. I had to make a little room by denting the corner of the opening . (see the picture) Winnebago Vista. Haven't traveled any where yet to check moving operation but standing still all sensors have been picked up by unit and showed I needed air in 4 out of 6 from sitting all winter. I know I'll feel a bit safer going down the road.
I installed this system on my class C motorhome. It saves having to verify tire pressure with a hand gauge and piece of mind that I don't have a leak on a dully tire while driving. You cannot feel a low or even totally flat dully tier, resulting in total shredding of that tire doing damage to the vehicle. This system was easy to install, keeps me informed on tire pressure and temperature. Instructions were easy to follow.
Eaay setup works great finally got a good one 3s a charm
We purchased the TST 507 TPMS for our 30 foot class B+ motor home with the additional 4 sensors to install on our Jeep Wrangler toad. I had to slightly alter the 16” steering tire Stainless wheel covers to make room for the air through sensors. The dual rear wheel covers installed without any sensor interference.
Once I got into a patterned routine I was able to program the 10 sensors without any problem. At first I programmed the high pressure too low and the high pressure alarms went off. I reprogram to 10% above the maximum tire pressure and the system works flawlessly. After loosing several China bomb tires over the years on travel trailers We now travel in confidence that we aren’t going to have tire catastrophes.
I really like the display and the ability to program multiple sets of sensors as I own several trucks and trailers. Its nice to be able to tell at a glance what all of my truck and trailer tires are doing temperature and pressure. I had a valve stem lock nut come loose and start leaking, saw the pressure drop on that tire and the temperature increase on the other axle, got off the road and repaired before I had a blowout and all of the trailer damage that comes with it. It paid for itself on that trip alone. I have since bought more sensors for my other trailer and for my other truck. Highly recommend it.
Purchased this tst system about a year ago, installed it on a 2017 ForestRiver Forester on a E450 chassis, my very first trip with this system installed save me from ruining a brand new tire that had an improperly installed vave stem that came loose, the system detected a fast leak, I was able to pull of the highway and call the people who installed my new tires to come and fix their bad installation, would highly recommend this system
Setup was easy enough that a non-techy person can do it. Readout is clear and seems to be fairly close to my tire guage. Within 2#s variance. I have never exceeded my alarm limits, so I'm not sure how loud the alarm is. I consider this cheap insurance. I have replaced the batteries twice a year as part of my trailer inspection and maintenance cycle. I would definitely recommend to anyone who tows.

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.
Worked as advertised. Purchased an additional 4 sensors for our towed vehicle. The system accommodates multiple configurations of vehicles and trailers which supports my original plan to alternate between a towed car and a trailer. Once all are programmed in, it is easy to switch configurations.

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.
TPMS setup and function reliably. The alarm is loud and cannot be missed.
But the display is weak and must be shaded to be seen. Disappointing as it is mounted next to my GPS, my ScanD, my backup camera and those are all easy to read
I did have one sensor fail and was very impressed by the assistance and speed of replacement.

Loving it. Now added fir the trailer. Just ordered a now-available sun shade from TST
I finally got a chance to use the trailer which has the sensors. It was great to find out the tires had lost air.
I was concerned about the sensors sticking out too far and possibly getting damaged when changing the tires. I decided to use the 90 degree valve stems. This was a mistake. The pressure on the valve, because of the leverage of the added length occurring with the TST sensor installed, cause the valve to leak at the rim. We changed all the valve stems to the short straight stems and now do not have a problem maintaining the tire pressure.

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 TPMS system works well. I had 6 on the RV, two on the car, and two on the tow dollie. The sensors are not 100% accurate but give a rough idea of pressure in the tire and temp. Always have an appropriate tire gage to get true pressures. The system did save us in NM because the potholes were so bad we broke a valve extension and an inner rear tire went flat quick. The monitor caught this and saved us a blowout. I just wish the sensors were 100% accurate otherwise it's a great system.

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.
Works perfectly for motorhome and Toad. Caught a slow leak (nail) while traveling cross country.

Oh man those slow leaks are sneaky! Glad this was able to let you know before something worse happened!
The system works great!
A must have when towing my new RV. Very easy to install and gives me piece of mind on the road.
Very nice system, and easy installation.
A friend recommended Etrailer when I got my RV. I needed a TPMS and after reviewing options and talking to the people who help you order these things, we selected this one. It was a LIFESAVER! Turns out we had a faulty valve installation from the new tires — but we didn’t know that until we had traveled across the entire United States and settled in at our new home. We traveled in May, but ended up driving through a blizzard and then a heat wave. The tire pressure was all over the place during our 6 week trip. Having this really made life much easier and safer.
Easy setup, and the trailer tires show up as well. I love how it shows the RV separate from the trailer
This was easy to set up for my triple axle trailer, This is the second TST set I have purchased. The color monitor makes it easier to see than the older basic monitor. Highly recommend this unit
Great system, replaces a cheaper tpms system and this is a much better option and screen is a big upgrade.
Easy setup. Definitely important to install and use the signal booster.
Work really well, just wish I could see all of the pressures at once but alarm surely goes off if one is outside of perimeters.

Work great…still wish I could see all at once
I have been looking for a TPM system for my 40 foot triple axle fifth wheel. I had a blowout last fall and it caused damage to the camper. This will remedy that situation. In the spring I'm going to have 14 ply tires mounted on the rims and the tire pressure sensing system will be added to the camper.
Very happy with how quickly the system was delivered to my home. It's just what I was looking for.

Very happy,they work great and help keep us safe.
Overall the TPMS system is working well. Had one sensor stop working. Did send it back and got a replacement. Other than that all good.
I love them. I took a long RV trip and wanted something to monitor my tires since I have a 6 tires to monitor. It worked perfectly and definitely is much faster than checking all the tires by hand. It’s a great product. I’m going to get some for my brother for Christmas too so he can monitor his flatbed trailer tires.
Do you have a question about this TPMS Sensor?

Great, as I stated in my first review it save me from ruining a brand new tire because the tire installer didnt secure the metal valve stem properly,I would not leave on a trip without it, great product, my only gripe is I didnt any O rings when replacing batteries, would purchase this very system again
