LOL, those same pictures get posted any time someone mentions bike racks and bumpers here, and at every other forum on the net. The fact is plenty of people haul bikes on trailer bumpers without issue. Sure, some RV manufacturers do a less than stellar job of bumper mounting and you can have an issue with anything, but hundreds of thousands of people attach bike racks to RV bumpers using some common sense and evaluation of how the bumper is mounted. Most owners never give it a second thought nor do they ever visit one of these online rags.
I've hauled a 2'X6' steel platform, using a bolt on Curt receiver bracket, on 3 different trailers. One I felt needed additional reinforcement at the attachment points, the other two I clamped on the receiver bracket and forgot about it. I also do not haul bikes on that platform but two RTIC 65 coolers that weigh 37 lbs each empty, and hold 70 lbs of ice.
People on these forums never cease to amaze me as soon as bumpers are mentioned, and the vast majority who comment and post those same pictures have never attached a bike rack or anything else to an RV bumper.
