The question also poped on Reddit after the project was showcased there and the man behind the stunt gladly answered: "I was bored and, I mean, everyone has a regular TJ pickup. I wanted to be different,"
For the record, this is a fully functional six-by-six, with the thing packing two transfer cases. The first is stock, while the second is a 205 coming from a 1960s Dodge.
Thanks to the addition of a hefty bed, the thing is now 19' 1" long, which, as the owner points out, makes it longer than a Ford Excursion. It is not small.
It all kicked off with a spare Jeep frame, axle and suspension, which were added to the back of the current frame, which meant stock TJ lift kit parts could be used, along with factory mounts for the stopping hardware and fuel tank.
The bed is fully fabricated (apparently, the aficionado grew up welding) and will receive a wooden floor. As for the cabin, this has received Dynamat insulation, while the closeout is custom (the top is an aftermarket Duster unit that barely fitted the cab).
All the work mentioned above reportedly took about a month, with the contraption now requiring body and paint efforts.
The aficionado quickly realized that the 180 hp 4.0-liter V6 of the Wrangler just wouldn't cut it anymore, so the man is looking for a 4bt/Cummins swap (the man is obviously looking for diesel torque).
As for how the thing handles, it turns out it's less than a nightmare: "Surprisingly, it doesn't plow you around corners like I thought. It sure as hell doesn't turn like the jeep used to, but I can K-turn in a driveway without too much difficulty,"
