Only issue I see is the cargo carrying capacity. Going off the FR site they show just shy of 1500lbs. All TT's will be heavier when delivered, thus reducing CCC. Most people take 1000+lbs of stuff with them, so both TT's will be near max when loaded.
Also the Rockwood has smallish holding tanks. If you never boondock and always have full hookups then all is good. But even with water and elec and no sewer the Rockwood will fill fast.
The WJ doesn't seem to have as much storage for clothes as the RW. They both have +/- IMO.
