Oh, yes, I plan to drive that truck like a half blind grandmother. Very slow, in other words.
Interesting idea, rbmggf7. If I get you correctly, it would be a rudimentary "I" shaped frame with the top and bottom of the "I" fitting width-wise from one side of the cargo deck to the other. Two 2X4's could hold the wheel in place, lengthwise, with a few short pieces attached in front and back of the tires to keep them further in place. Sounds do-able, with the help of my friends (and their tools).
Check, andy750. I will totally avoid using an old door as a ramp, or have pygmy women help me unload it. Heh.
