Second to last year 3rd generation Econoline E250 - Quadravan conversion, which was done when the vehicle was new, by a company called Pathfinder. They would take these from Ford dealers and add a lift, 4wd with 2-speed transfer case and upgrade a bunch of other components like the axles and drive shafts, change gear ratios etc.
This was made into a bare-bones camper van back in the early 90's, it has a bit of a vintage/kitschy interior vibe
