According to the manufacturers of bike racks, the motion on the rear bumper of a towed car behind an RV is subject to greater sudden left/right and up/down movement than is seen on a driven car with the same rack attached.
This leads to bikes hung off of the back of a toad to stress uprights and hangers much more dramatically, leading to weld and metal failures.
It's very similar on the back of a travel trailer bumper as well.
