I have posted several times about getting and older SAT dish to work. Solved the problem today by buying another coach. The "new" coach is a 07 HR ambasador. It does not have a brake controller for a ...
I partially agree. I would want the trailer braking if the eng/exhaust brake is actively slowing the MH. However, on long grades, constant braking on a trailer could be a problem. A better-quality controller can be adjusted for this.

OP would just need to be informed on how his MH is set up.
