Very strange that the bike was on a bike rack on roof of motorhome. What kind of motorhome has a bike rack on roof? Even on lower profile van campers, most owners don’t place bikes on roof.
It’s always best to keep expensive bikes out of sight. A lockable bike garage not only deters theft, but protects bikes from weather.
Thor, if reading this forum, it’s never too late to offer an Axis/Vegas touring floorplan with a bike garage under the rear Twin/King beds.
