Mine handles like a comfortable U-Haul; it's a truck, but it doesn't beat one up generally speaking and is not especially exhausting to drive. If the road is rough enough, of course, you do get bounced around...in most any vehicle, to a greater or lesser extent.
Gas class A's don't have a vastly better ride; the Ford F53 chassis they use is generally similar in many respects to the E series van chassis (or the Chevy van chassis). Diesel pusher class A's with air suspension do have a significantly smoother ride...and cost significantly more, of course.
