there are a variety of things you can do. First is have a cutting frenzy week (s). Cut all the parts, put them in large bags with patterns and thread and vacumn seal it. You would be absolutely amazed at how many can fit in a stack. When you get your fifth wheel, look for places to build. We raised the bed in our rv up 5" on a platform. No one really noticed and the quilt top covered it, but boy could I stash stuff in that big space - cutting mat, scrapbook containers full of sewing notions, etc. you may discover you don need all the kitchen places for kitchen items if you are only cooking for 2. It becomes a question of what is more important. The money you get from selling your 'extra' fabric you can use to purchase backing and batting as needed.
