http://s908.photobucket.com/albums/ac281/padresag/suburban/this is how I lifted this one off and put on a dolly. I removed the doors and strung a double 2 x 8 and tied to the roof in the frt door frame(needed double for height) and the ran a 2 x 8 from the rear over the top of the 2 x 8 and then used plumbers hanger strap to secure it to the top of the rear door frame. then used the motor lifter front and rear to get it jacked up to height to slide the frame out. then lowered it down for the dolly.
am going to part that body out as I have a much better one. which is going to replace my old panel body which was on an orig 4 x 4 frame.
hope this helps
