I like the idea of a ladder to get to the roof. I don't like that you lose 12"-18" of the glass opening. I've seen a side ladder, but it was a full rear bumper replacement, which I actually like, but it's a waste of money for me because I don't need all it consists of. Is there an option for a half ladder? From bottom of hatch to bottom of glass. Not even sure there is even anything at the bottom of the glass opening to attach to.
