It's standardized that way because it's easier for upfitters to work with a C-channel. They know regardless of the brand that it will be flat with 34'' spacing. The only variables they need to work with are the Cab-to-Axle measurement (distance from the back of the cab to the centerline of the rear axle) and whether or not they need to use a PTO, and which side it's on. Fully boxed is more suited to pickup trucks than chassis cabs, because the rigidity improves handling and ability to go off-road without twisting the frame. Chassis cab buyers don't have as much of a need for that.
