That is one of the major reasons we have not traded our 22' TT for a little longer one. Our Sunline has a light maple interior, which we love, and real wood too. But it only has a dinette and we would like to have dinette and a couch or two reclining chairs. All the new TTs we looked at have dark cabinets and dark wood finishes making the whole interior much too dark. That is a deal killer for us.
Another thing that gripes me is most of the mid size TTs, no matter the manufacturer, can not be had with the finer interiors upgrades that the longer TTs have as standard or optional packages.
