I held off posting this for a variety of reasons - first and foremost, I was trying to buy it (and I did buy it yesterday) and did not want to generate a bunch of interest and simply out of respect for the owner.
So here it is. What I can tell you is that it is NOT a genuine Ford product - the bed is 100% aftermarket conversion parts but is very well done. It was apparently made by a company called Recreational Designs, Inc out of White Pigeon, MI. It is all fiberglass, including the tailgate. I think RDI probably added the visor, graphics and handles as well.
I first saw this truck about 10 years ago and thought it was super cool. I spotted it again about three months ago sitting by a garage with four flat tires and weeds growing up around it. I left a note on the door of the house stating that I was interested in buying it and the owner called me in July to say that it is in fact for sale. Several weeks and some negotiation later, it came home with me. This was apparently the PO's father's truck. It was purchased new locally at McKie Ford and was daily driven up till 2011 when a new vehicle was purchased and this was parked and left to sit there.
Unfortunately it is not in very good shape - the doors and front fenders are quite rusty, it needs tires, a windshield, battery, exhaust work, rear axle seals and probably new gas tank & pumps.... but it actually fired up and I drove it off my trailer and into my shop!
Specs are pretty basic - 2.9 V6 engine, 5 speed trans, push button 4x4. It is an XLT but is missing cruise, AC, PW/PL/tilt and that's just fine with me.
Enjoy - it may not be the incredibly rare Shadow prototype but I'm guessing it's the next best thing and we may never see another.
