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 ran D tires on smaller equipment/cargo trailer carrying close to max axle loads and on hot 100+ temp days psi went to the 72-75 ranges. Sound like you need a real TPM system for full size trailers.
