I agree Bill, I could see doing 1 bike on there, then one on the trailer, but 2 bikes trailer is well in excess of my 500 pound load limit.
Plus, it looks really busy back there- any sharp turn and you'd crush the bikes with the camper.. as it is already I have to watch one of my tail lights when backing up, or it'll hit a tie down bar for the bike mount on the trailer. One of my motives for just modding the camper is getting the bikes back and out of harm's way when towing, plus allowing for access to the rear hatch even when it's all hooked up.
