Looking for what others have found to work well to transport bicycles. Currently we transport at least 4 bikes and sometimes 5. We have a DraftMaster, which is a hitch mount and which works wonderfully! Looking for other ideas though, if we tow the camper our hitch mount cannot be used for the bikes.

Has anyone used a system that will mount to a flat truck Tonneau cover? Similiar to a roof rack system typically used for a car? I've tried searching and haven't come up with many answers.
