Class 8's don't typically run a rigid frame because of the up-fit market. No class 8 manufacturer owns enough of the market to build their full-on accessory line economically. Notice that even CC trucks have their frame rails at 34". Same with all the HD trucks moving up in class. Again, this is so that all the up-fitters can design their upfitting packages on 1 single platform. If only 1 manufacturer built a fully boxed frame in that HD class of truck, how many up-fitters would be leaping at the chance to work on that 1 tiny segment of the market? Vast majority of those trucks are road trucks as well. For the class-8 trucks that really go on the rough roads, they Double the frame kinda like this: [[ ]]. This is so they can maintain compatibility with the up-fitter market and still have the rigidity they need their trucks to have to survive.
