Have seen once rolling down the road. Not mine, just FYI.

I wonder if that 12-" is a typo, but from the pictures it does look like the cabin is wider than the truck itself, which is supposed to be 96".
Building it intentionally over the legal width, if that what was done, was negligent at best.
I still want to drive one for a few minutes, just long enough to entertain myself. Certainly not across the country.
