We have a 2013 big horn and we elected to have the class 1 hitch installed at the factory when we built our coach. All of the 2013 have "L" brackets on the rear of the frames where this hitch can be bolted on. I realize this hitch wasn't meant for any use other than just a bike rack, due to its rating. Anyway the hitch becuase of its width is very "spongie" when loaded with just our two bikes. It flexes in the center, up and down, I think too much. I have pretty much decided its not worth using. We used it once and the bouncing motion of the rack in the hitch damaged the receiver. Just an FYI to all that might think about getting one. Its not very robust, and there isn't really any re-enforcing plates welded in the center. I would take it off and weld some re-enforcing plates on it, but the "L" brackets mounting it to the frame on the rear... aren't all that heavy either.
