I have owned a standard Class C listed at 31' but actually 33' on a Ford E450 223" wheelbase chassis. We now own a Class A DP listed at 33' but actually 34' on a Freightliner 208" wheelbase chassis. With a standard Class C the ride is harsh and noisy, the payload is poor typically 1,000# - 2,000# payload. Handling is typically poor. Typically they can only be used in summer months due to lack of enclosed tanks or plumbing. The other difference is the turning radius. Our class A has a much tighter turning radius with a 55 degree wheel cut and a 208" wheelbase than our standard Class C with a 223" wheelbase and a 45 degree wheel cut. Super C motorhomes are a different story however have some of the same noise and heat problems as well as the turning radius issues. However they don't have the payload problems that the standard Class C units do. We like the air ride suspension and panoramic view out the window.
