Truck for hauling bomber parts. Two engines on some models! I like how the engine tray slides out.
Further along in the COE development you have these beasts, built for the military to haul bomber parts. They must have encountered engine access troubles- before the invention of the tilt cab (I think?)- and designed this sweet slide-out engine tray. Wish my truck had one. Some of these bad boys had two engines, and two side-by-side rear ends, like in the last photo.
