That first one might work. I can't use the second one, my bike can't stand up in the bed of my truck with the topper. Was looking at this Allen Sport rack as well. Something that swings out or down so I can lower my tailgate. I just don't know if this will rub the paint off the frame after awhile?

My "platform" rack can also have the "tower" part swing down out of the way (when no bikes are on it), but I never need to bother with it, I can still access my trunk. The platforms can also fold up to the center. I can't say if all the platform styles can do that or not.
That one that you linked is the "bike hanger" style that I mentioned--I prefer the platform style. But, if you are saying that you want to swing it down out of the way while there are still bikes on it, then the hanger might have that advantage (but check up on it, I have very little experience on the hangers because I use the platform).
The 2nd one might still work with that camper shell, the bike won't be as tall with the front wheel removed.....but, it's probably a big hassle to crawl in there and deal with it.
I don't understand your concern about "rubbing the paint off the frame"??? On mine, my bike never touches the frame or the body of the car, and the rack never touches either of those either. I had to install a trailer hitch (hidden hitch) to the frame on my Mustang. I line up the rack, give it a kick to insert it, then 1 bolt holds it in place to the hitch. To me, the simplicity of 1 bolt and the fact that the rack never contacts my paint makes the hitch-mount the only way to go (forget about the trunk mount with straps and hooks crap).
By the way--Nice Truck!
