I have a garage,but its not big enough to take a truck cab off in,so all the cab swaps I've done had to be done outdoors anyway--you can see better outside,and you need lots of room for the assorted timbers and the hoist,so dont despair about no garage. I have a A-frame thing that used to be a swingset at a public playground,its made of schedule 40 2-1/2 inch water pipe,I've picked up many cabs,engines,tranny and tranfer cases with it,even one end of my truck when I swapped rear ends,with a 2 ton chain falls on it there isnt much you cant lift,and its very stable and safe--I helped a guy do a cab swap with only an engine crane,it was not much fun,in fact we almost dropped the whole shebang,and ended up using a pair of floor jacks and 4x4 timbers to jack each side up little at a time,until we had it high enough to clear everything,then we rolled the chassis out from under it.The A frame is much easier and safer.I've seen the "shadetree mechanic" approach using a large tree branch and a come-along or chain falls,but make sure its an oak tree with no rot,and the branch is at least 6-8 inches thick--and dont trust it completely--cabs are pretty heavy,even stripped they weigh about 400-500 lbs. /forums/images/graemlins/yikes.gif
