Is this tail dragging an issue for all short Class C's or only certain ones. I notice some rear overhangs taper up slightly from the rear wheels and some have a more defined taper starting half way between rear tires and back bumper. Is one a better design than the other?
The older Four Winds certainly were designed with a long overhang, as shown by the OP's original image:

Ours was 27'; it had that long overhang as well:



I had those airbags inflated to maximum pressure as much as possible:

Our Sunseeker on Chevy is 24'; due to the shorter overhang and the lower frontend typical of GM's cutaway chassis, we've never touched the tail on any surface:


It all depends on the manufacturer, model and the chassis.
