I strongly suggest the Bones rack: I drive like an idiot, and my
bike weighs at least 50 lbs., and I've never had a problem!
I use our Chevy Trailblazer's hitch rack mostly, and in fact a few
years ago, a gentleman on this site welded framework from
in front of the axles, below the frame, and out the back....
on his SVX, so that he could have a hitchrack. It was beautiful, but a little too permanent! He carried a windsurfer, and was Australian. Good luck!
