Some idiot lost a bike off a truck mounted rack from his sedan last year. I couldn't avoid it, and ran it over with both driver-side wheels. No damage to the Mounty, but it took out the front, bottom corner cap on the camper, and took at gouge out a brand new trailer tire. Could have been a lot worse.
When we take bikes anywhere, and they are not in the camper, they are securely mounted with the Thule roof rack. Worth every penny.
PS - If anyone must use some flimsy hanging rack system (even if it's a good name) at least put a cable lock thru the frames and attach to something solid. At least then the people behind you will have some more warning before the things come loose.
