LOVE IT! Really nice looking, perfect, I'm jealous!
How strong is the tubing? If stronger than the mounting points I'd be extra paranoid about rear end collisions, or backing into something. It would almost definitely crush the mounting points on the body, then it's a whole lotta work to get that lined back up if you ever wanted to put the rear door back on.
Not saying I wouldn't do it, because I WOULD if I had that skill, but just to be extra careful and cautious!
and I vote for matching size spare/tire in back! Either that or a rear facing seat, like a gunner turret on the bottom of an old WWII bomber!!!
