Rear view camera failure...what to replace it with?

Get a wired system and mount it inside to view through the back window. I mounted the monitor on the rear view mirror and have at least 5x the view I had with the mirror in my class C. It is invaluable and cost about $250. No holes to drill or water seepage problems.

That would work awesome, if the toyhauler had a back window. But you just gave me an idea on how to mount one on my horse trailer! Thanks! I'd never thought of mounting one that was vs. drilling holes thru the exterior.
