Class C's have stiff springs in the rear and these give a jarring ride over cupped concrete highways damaged by weather and big rig trucks. On smooth blacktop the ride quality is much better. Big slab-sided vehicles are bounced around by wind turbulence and passing big rigs, expensive add-ons can improve on this.Maybe short Class C's (22-24 feet)ride a little better. I take claims of Class C's riding like an SUV with a grain of salt. I'd drive and compare Ford and Chevy C's ride and handling before buying.
