Is there an easy way to align the front of the camper?

Since the truck rotates (almost) around the middle of the rear axle, it seems like if the axle is centered left/right with the centerline of the camper a sharp turn of the wheel should fix the alignment. It might take going forward, reverse turn, backwards to stay on the centerline. So far, my experience has been that this will correct some alignment issues, but the bed is so long and clearance on the sides tight that I have to pull most of the way out to even try this.
