I have had mine for a few years. On my other motorhome I kept losing connection to one of my sensors so I got the Rhino booster from them. It has worked great since then.
I installed the booster to the under side of my battery compartment with nuts and bolts and ran the wires directly to the house batteries with a fuse inline. It was easy and on the Challenger 37KT it is centrally located front to back and works great.
