We have the standard 2552 and the ride seems reasonably good. We have never noticed any significant push or sway resulting from being passed by a semi or large class A MH. We do notice more roughness when on segmented roads, pot holes, railroad tracks, etc. We have made a trip from the east to the west coast, Florida, and other shorter trips and find the 2552 comfortable to ride and drive. I would expect the ride and highway drivability to improve with increasing wheel base length. We stay frequently in National Park and National Forest campgrounds which typically have shorter sites so I think the 2552 is a good compromise length.
