If its on a '70 ford 1/2 ton frame I don't see why it would be better than a Power Wagon. Now if it were a 3/4 or 1 ton frame (F250 or 350 vs the F100) then it'd be closer, but the old Power Wagons are a force to be reckoned with. Coming from a guy with a '71 F100 4X4 in his driveway mind you.
Its definitely a good looking truck though!
