Hi Jim!
Thank you. Well, I think that a REAL VW transporter would have a lower platform than my fantasy build, as is the case on their pick-up. A fellow modeler inspired me with his creation: a blue transport truck of the same configuration (with tank tracks), but his' had a tarp over the rear "box". I'm sorry that I can't remember his name right now, but I'll try to locate it in my old Contest Annuals and report it here later.
That being said, my concept could work. The driver would only have to be prudent with speed (hence the 20 MPH Club!), because the center of gravity would be fairly high. Luckily, ample turning radius is possible on most dry lakes! And it is pointless to repaint every year, so...
