Just looking at the photos, it's ground clearance seems too low. The entry door step mechanism also seems to hang down even lower than the walls of the coach. This would make it suitable for only paved and level road surfaces - plus be a problem exiting/entering streets where you have to drive over rises/dips for water control.
Also ... what extra weight carrying capacity does the chassis have over how much the coach itself loads the chassis? Possible reasons for chassis overkill being desirable include things such as - over what's required as minimums - more robust braking, better engine and transmission cooling, less rear spring sagging with age, and overall greater chassis strength carrying the coach and it's contents mile after mile.
I guess it boils down to does one want good, or better, or best in all aspects of what constitutes a great RV.
