How long is that? About as long as your regulation pickup, or bigger?
It looks like it could withstand even me.
Until recently, I would've said it was bigger than the average pickup, but some of the newer 3/4 ton rigs like the Ford F-350 Super Duty might actually be bigger. There was a "stretched" or long-bed version of the M-37, as well as the enclosed, long-wheelbase ambulance version mentioned above in the thread. There are websites devoted to the M-37, so the overall length and width should be easy to look up (for comparing with, say, the inside dimension of one's garage).

Well, if you like manual transmissions, it might be just what the warrior princess ordered! You'd have to learn the art of double-clutching, though - IIRC, these old Dodges had unsynchronized gearboxes.
