I think I saw something similar, it didn't have the turret on top, parked someplace along a 2 lane road North and just a bit East of Minot ND. If you would like pictures let me know.... I will be going through there in the next week or so.
I did read an article......click and clack or some thing along those lines.........they just recommended buying an old Chevy van and taking off 2 of the spark plug wires, as I recall it was the feeling of driving a VW van, but you had a bit of a safety factor.
