I took a 12.5ft long grain box off a truck frame and put it on a dolly for a while till it's ready to go on my truck. All I used was a come-a-long and a couple guys with strong backs. Take off the U-bolts. Line up the two units and hook up the come-a-long and go for it. If the bed starts to come off the frame rails two or three guys can slide it back in place, provided you don't completely fall off the framerails. I'm 24 and my cousin, brother and I pull this kinda crap all the time... usually with out expensive equipment. Every once in a while we have to get out the cherry picker or back hoe.
