LOL, wish I had a lift like that in my garage. Would make it easy to work on the engine if I could lift the body like that. Much better than trying to work on most modern cars where everything is crammed into a tiny engine compartment and next to nothing is easily accessible.
Although even without lifting the body, there's more room to work on the Wagoneer with the 5.7L V8 than most every vehicle I've owned (newer than the 1960's or so)
actually its quicker than pulling the engine out the front. They figured that out on the old Diesel Rams(used to do it myself back in my tech days). You can undo all the cab mounts and such in about an hour, versus having to pull the front clip and deal with all the trim pieces fitting back together and such. There are around 6-9 body mount bolts and a handful of electrical harnesses.
