the XJ i picked up, was built already. got it to replace the RZR, wanted something that had heat, more comfortable to play with in the winter, and could plate to take down the road.
gmc 2500, started to SAS it, had the front mostly done but lost motivation so started robbing parts of it for my red truck rebuild. been sitting in the back corner of my shop for the last handful of years unsure what i want to do with it. might get the lift done in the back end soon and decide if i should keep the tons under it and rebuild them or throw the set of 2.5 tons under it that i have in the back of the shop as well.
spun a bearing in this last fall, haven't touched it yet though. picked it up in alberta about 5 or 6 years ago, the more i started going through it the more work i found it needed. ended up redoing
everything on it except the frame, body and front bumper
454/th400/205, 60 in the front 5.13's with a lunchbox, 14bff in the back 5.13's, yukon grizzly and a disc swap, 52's in the front, crossover steer, 56's in the rear with a shackle flip.
i've been trying to figure out what a workable 'goal' shop would be for my 40 ac hillside. 
seems like the big hefty metal beams like that would also make it super easy to service a large amount of the shop with an overhead trolley hoist. even a 1 ton chain model would be handy
