Well mechanically they're identical. However the Super 12's were much more luxurious than the suburban 12. The super 12's were top of the line. They featured fancier hood emblems, A deluxe steering wheel and seat, Wood grain detailing. And of course the Cigarette lighter. But as far as engine, trans, and frame. They're the same. I have both and they are both the same.are there any differances between the two other than appearance?
