have you looked to see if they still make the Rockwood twin of this trailer?
personally, i wouldn't worry about it not being produced anymore.
Flagstaff and FR are still in business, it's built with the same materials the others are, the appliances are warrantied by the their manufacturer.
i almost bought a Roo floorplan that had been discontinued. only because they came out with a better one, did we change our mind. if the 23SS hadn't come along, we would have bought the discontinued model and not worried at all.
and we bought ours from a dealer 2000 miles away.
never had any issues finding a dealer near us to do the warranty work, with FR's assistance.
