The door on my
Boler is way out of whack and wife said she thinks it is due to sags in the fiberglass/plywood floor that makes the whole shell dip and sag in different places.
The frame is factory straight, but looking at whole shell one can see sags here and there looking at the bottom lines, especially looking at the rear and front.
I do think PO did some hinge work on it and didn't get it right but I can live with it.
