put my truck on a lift under the body, raised it and rolled out the frame. problem is it's far from the crossmembers down to the edge of the body, so you really have to block the body up high. I made a rotisserie out of wheels and hubs with pipe running from front set to rear. used cranks off a tractor trailers legs with a wheel with holes in it so i could rotate it.
