Anything on the back bumper adds lots of torque which can either cause the bumper to fail or bend the frame. The smaller lite weight trailers are much more susceptible. As you consider responses, be sure to take into consideration the type of RV the responding member. As mentioned there are some members who have had good results and some who have had poor results. If you do add a bike rack, be sure to have someone tow the PUP around with a bike on the rack and follow it. Then determine if you want your bike on it.
