I owned a 96 Jayco 28rks. It was,ok on good roads, but it suffered some structual problems (slide operation failures, broken springs, worn out suspension, and rain water leaks) during a trip to Alaska. We downsized to a 21. 5 Nash and I think it is much better structually. No slide though, and that makes structure integrety easier. The Jayco was a bit fancier, but if I wanted nicer furnishings I'd have bought the same unit in Artic Fox. These things really seem to hang together on very bad roads.
As previously stated, look up the Consumer RV rating reports. Lots of good info there.
