I am coming up on a similar situation and was really interested in the park models. They are roomier and much less $$. My biggest problem comes with resale. There is VERY low demand for new ones. Even less for used. I found the net to be full of ads that had been on for a LONG time with crazy low prices.
If I could commit to actually leaving the thing sitting in one spot or moving very occasionally, I'd go for it. But life and plans change and I just don't want to drop 50-60K on something that depreciates (even worse than a 5th wheel
)
As for the original question, I've looked at Riverstone at shows and they are super nice. I generally agree that they are at the top of the price v. quality list.
