Thanks for all the replies! Great information so far.
In my situation, the entry door to the camper is on the side of the camper. So I don't have a concern about the bicycles obstructing entry. But if I mount them on the back, the rear slide out hitting the bicycles is a concern. If the bicycles are mounted low low enough to clear the slide when it opens, they could hit the ground on a steep approach, if they are high enough to clear the ground in any situation, the slide will hit them when it opens. So something movable would be necessary.
