Here is a pic of the Swagman 2 bike rack I had on my hybrid trailer. When the rack was folded down the bed cleared by a few inches. The bracket that supported the rack had to be custom built to fit between the battery box and propane tanks.
Here is a pic (sorry the best I have) of the bike rack on our new Starcraft. I have a hitch welded onto the frame of the trailer with a piece of 2" square tubing bolted to the hitch. I have then attached two Swagman RV racks to the tubing so I can carry 4 bikes. It is a very solid rack with no extra bouncing to stress the system. Towed 4000 miles with it so far.
I eliminate all of the movement in the hitch with this.
