I think that making the Nomad liftgate/tailgate one piece with hinges at the top and keeping some style to it is darn near impossible.
Rick, I tend to disagree. I don't think it would be that difficult to do, and it's been done before. I'm pretty sure I could do it if I wanted to. Heck, Chevy did it with the delivery!

I think a roll-down window would be a lot harder to do.
