longorn body question

[jd4300fel]

I have a question on the body alingment of the longorns/camper specials.
I have spent the better part of yesturday trying to line up
the body lines on my lonhorn.
after lots of fustration i finaly put a level on the seam were the
additional section have been added. on the passenger side it is level down the side of the bed, but with a level on the top of the bed side theres a 1/4
inch drop, on the drivers side it goes up a quarter inch. as well as it dips in at the seam. any else seen this, if so how did you deal with it?
