As I said, I depend on my mirrors, not my electronics or my ears. Radio playing, windows up, etc has no impact on my ability to back my trailer into the RV building. But even if it did, the mute button is pretty easy to push.
I can back ne thing up, learned long time ago, the smaller the trailer, the more difficulty also. Them friggin 1/4 ton trailers were a monster PITA, lmao.
ADDED: Mirrors are great for sides, not worth a heck behind the trailer, HENCE the mark on the floor, since trailer is a 14' Stock, no rear sight age, hee hee. But then all good, all depends on each individual situation.
ADDED: Backing them 3/4 ton trailers behind a deuce with manual steering was always a workout too, hee hee, but BOIRD was a younger gobbler than. Not like all these newer rides with automatic, and air up/down tires, monster mirrors, etc etc.
