A major part of my travel enjoyment is to take our bikes out and explore. It is about the only exercise my lazy bones get. It sounds like you enjoy biking as well Doug.
The way I figure it, the rack and mount will not hurt anything on the Monte, and the frame issue will probably never come up. If it does, I will deal with it, meanwhile, my bikes are with Sue and I for our enjoyment.
As Mudchef stated, my pictures are beneath my sig.
I elected to bolt mine on myself, any hitch shop can do it. Many state that the rear stabilizers have to be moved to make room for the hitch assembly, I made mine work without the move.
Good luck.
