Hi, I just purchased the Xport fork mount roof rack for my 97 Honda Accord 4 door. Has anyone used this rack? I'm having some trouble installing it - it seems sturdy enough (it survived a 12 hour thruway trip), but the hooks that attach under the door don't lie flush with the roof. I've heard stories about this rack coming off while driving, so if anyone has an opinion, I'd be happy to hear it. I might spring for the Thule feet, since the parts are interchangeable, but that's another $150.
