We own a 1997 2720, and visited with someone else who had a newer model 2720 (2001, I think) before we bought ours. Our floorplan is just like theirs. From comparing the brochure that we found in our TM with the factory specs page, it doesn't appear to me that the floorplans have changed since then.
I believe that our 1997 is very well and solidly made. Things that people complain about with the newer models (screws coming loose, stove coming loose, problems with the refrigerator, cable connections) haven't been an issue for us. We've broken a couple of things that we've had to fix
) and have chosen to make some modifications, but we would buy it again in a heartbeat.
