RV Tire Pressure Monitoring System, RV TPMS, 4 Sensors, 7 Alarm Modes, 14 Days Battery Life, 80ft Sensing Distance, Large Screen, for RV, Trailer, Coach, Motor Home, Fifth Wheel, (0-188psi) (-4~ 185℉)

Nice to have information about the tires. As a friend of ours had a blowout in their RV in heavy traffic. The alarm has let us know we need air when getting started on our adventures with our travel Trailer.

Bought the 12 sensor kit and all work as expected. Installed them on a 44 foot 5th wheel camper and was able to get readings without the repeater. About 45-50 feet between camper wheels and display. After 2k miles, I only experienced a couple of brief, single sensor, outages. Nothing to be concerned with. Sensors would come back on and worked flawlessly. The battery in the display unit lasts a very long time as well.My only complaint is the backlight. It is light activated, meaning the light turns off during the day and there is no way to turn it on other than covering up the light sensors. It's difficult to read without the backlight. Even with the backlight I find it slightly hard to see during the day, but I am old, so that may mean nothing. Regardless, a way to manually turn on the light, and possibly adjust the contrast may be useful. This is the reason for taking 1 star.

My friend talked me into getting this for my boat trailer to monitor the tires. I tried this out and worked as expected which rotated around to display to the stats on each tire. I also just purchased a 27' camper trailer. As soon as it warms up from the deep freeze we are in now and we can go camping, I can't wait to try on the camper too. I'm hoping I don't need the signal extender for the camper, but if I need to I'll order that. Based on what I've read I'm under the distance and may not need the signal extender.I definitely want to use while pulling the camper trailer after seeing first hand the damage a blown out tire can cause to the side and underneath of a camper wheel well area. I'm sure a tire monitoring system would have alerted them of an issue about to happen and could have avoided. Now any monitor does not replace good judgment and tires rated for the weight and speed that you need for your hauling experience. The tire monitoring will help me keep the right tire pressure and alert me to issues before they become serious.One thing to know is don't rely on the YouTube video reviews to know how to use. I was getting stuck and decided to actually read the directions in the included user guide all the way through first and then follow the directions from the beginning. The directions are clear, you just need to take you time to read them, which if hard form some of us. This helps if you happen to start playing around with features and may not be in sync with a video. I will though have to admit the YouTube videos are what helped me decide to purchase.I like that kits included are extra O-rings in addition to the ones already on the sensors. I'm guessing I'll not need those new O-rings for a couple of years, but nice to know I have them when I need them.4/3/2021 Update: Over spring break I was able to get our new 27' camper trailer out. I programmed all 4 of the sensors. I hook up the truck and turned the receiver on. After about two rotating scans all sensors were sending reading to the sensor I mounted high up by my rear view mirror. When driving down the road for just about 10 miles I could see the pressure come up gradually about 3 psi just from driving. I did not charge up the receiver since my initial charge and still has a full charge without plugging into the truck's USB. I'm guessing the unit will at least last a full days drive, but if needed I'll plug it in.I don't plan on leaving the sensors on the tires when in storage. I am making the assumption that the batteries of the sensors will last longer, but not sure.

Installed on Entegra AnthemDEQ. All worked as described. We have not traveled yet with this tire pressure monitor yet. Will update if requested in the future.

We just got this, and so far are quite happy with it. We installed sensors on our 35' Class A RV and towed vehicle, the toad required the included booster, but that was easy enough to wire into the 12V RV system. I at first installed it just before getting new tires because I had been having random blowouts (tires were just at the end of their time), got it all configured. A few days later we installed all new tires and they removed the sensors for us and reinstalled them, but not in the correct order. It was very easy to go around and re-code the sensors by just selecting the correct tire and walking around to re-attach each sensor.We've had it alert us to 3 problems in our travels so far:1. On our way out of state, the system told us that one of the tires was at max pressure, so I pulled over and let out some air to bring it down to safe levels. The tire shop had inflated it to 85 psi cold and once it got warmed up it was over 100 psi.2. It notified us of a fast leak on one of the front tires, which ended up being a loose valve stem that had just worked loose over time, the weight of the sensor probably just caused the (very loose) stem to lose air.3. On our way down a mountain the front brakes heated up because we were winding down very sharp turns that even downshifting didn't keep us going slow enough, and it let us know that the tire was too hot so we could let it cool down.Also, when you take off your toad, you can easily take the unit with you, very easy to hide either the RV or the toad with the press of a button.Now and then, you'll have a sensor that seems to go to sleep, but they'll wake up again when you hit a bump, so not a big deal.Also, if you're like me and not used to monitoring your tires full-time, you learn to not be worried as the pressure and temperatures rise and fall during trips. It'll tell you if there's a problem (or has thus far).Update: You're not able to set the pressure lower than 21psi, the monitor will alarm at that pressure even if you set it to 22psi, which is the lowest limit. The car we tow behind our RV is an older SUV (Geo Tracker) and the tire pressures are supposed to be 24psi on-road. Off-road they should be more like 15psi. Using this TPMS for the car is irritating because it only seems to have a 2psi tolerance for pressures in the range that the car needs.Also, there have been a few times where we're on the road towing the car and for now apparent reason, the system will hide the sensors that are associated with our towed car (the trailer sensors for tow-behinds and 5th-wheels). For us it's just an annoyance when it happens, I can hold the '-' button and it will show up again, but then sometimes it goes away again for no reason. Since that seems like a huge deal for a lot of people, I'm gonna have to take off 2 stars. This system just costs too much for the aforementioned issue with lower PSI pressures and trailers. :-(
