If you drop the tounge ~4" you can get to around 83" at the tower hinge. I've seen some hitches that are adjustable on the fly. I've got a 00 z71 and measured it for a guy that was looking into buying my 21v (which is still for sale
). It was measured on the truck with a drop hitch just to see if it'd work. However, I've never tried to get it in a 7 footer.
