At first glance this may look like an original Econoline pickup, but its a home-brew imitation. And not a bad job at that, although one does kind of wonder why. Maybe it got damaged back there, or the pickups are hard to come by. Or?
The cab of the factory pickup went back further, to encompass the engine compartment. Here, a heavy-duty fabric curtain divides the cab from the load bed, and part of the engine still sticks out.
Here’s where this one has an advantage: opening side doors. And it looks like they still work pretty well. Shades of the Corvair Rampside.
