For some reason the right side of the bed sits higher than the left. Body lines line on left side but are a hair off on passenger side. From the rear it is VERY noticeable. But the truck runs straight as an arrow. Any ideas as to what might have caused this? Trying to see what I need to do before I get a cage in it. Because I hate to put it in with it like that. Would you just get a different frame that is for sure straight and just do a swop? Or let the body shop put it on the machine and straighten it? Thanks in advance.
