I bought and have been using the TireMinder Smart TPMS system for the past two years. I recently bought a different Toy Hauler and two more sensors, since the new one is a triple axle and I now will monitor 6 tires instead of 4. No worries though, the TireMinder will monitor up to 22 transmitters. The big advantage for me is that the Smart TPMS does not have a dedicated monitor for putting on the dash/windshield of your truck....you use a phone app. The booster is mounted on the front of the trailer, and the Bluetooth adapter is suction cup mounted in the rear window of the truck and can either run on rechargeable lithium batteries, or plugged into a USB port. The B.T. adaptor also has a beeping alert built into it, just in case you want to open your phone app for monitoring, but let the phone go into sleep mode....you will still an alert. If you do, just wake up the phone and look to see what is going on. Lot's of good ones out there, it's just of matter of preference sometimes.
