I went FR3 30DS because of the floor plan and the desire to stay at 30' for restrictions at some state parks we enjoy. I think it is the best 30' floor plan out there from our search. Had I gone bigger, I would have shopped around more and looked for a full fiberglass roof as noted above. If length is not an issue for you, shop around. Not knocking my FR3, but there are better coaches out there for a little more money.
