I'm guessing that you're looking for a way to use your dinette table for eating and also for sleeping? If so, Keystone used a folding table base in the Springdale line for a few years. I'm not sure if they still use it or if it's now been replaced by something different. We had it in our Springdale fifth wheel and it seemed to work well both as a table and as a part of the bed platform. Additionally, since it's a free standing unit with the tabletop attached, it can be used outside if desired. We never did that, it was too much hassle to unload it and then take it back inside later in the day, but it was an option for outside use.
