I'd like to see some of your methods of attaching bikes and/or the rack to the back of your RV. I have a normal bumper-hitch type bike rack that we used on our old Van. Like this: I wanted to use it for the trailer. So I got a welder friend to attach a receiver onto the RV bumper, but with the weight of the bikes and no support up top, the leverage and torque of bouncing down the road made the rack "peel" the bumper apart. No that's not the weld coming apart...that's actually part of the bumper material peeling away: SO....what methods do YOU use to attach your bikes to your RV. I'm thinking of taking that receiver off and welding it to the TOP side of the bumper...and then attaching some support of top "bracket" to just bolt into the rear of the trailer wall.
