So we are new owners of an Grand design Imagine XLS 21BHE. I would like to get a TPMS, but want a small footprint in the cab. I am thinking of the TireMinder Trailer TPMS (https://www.tireminder.com...
I’ve had the Trailer version for about 3 years now and it has worked well with both 50psi and 65psi tires. It does have a limit of 70 psi, but I’ve never had a problem with that. It does read about 3 to 4 psi lower than my air pressure gauges do. My son has 65 psi tires and the same system. No problems, either.
