Need Curtains? Take the old ones to an upholstry shop. They do RV interiors and make curtains all the time. Don't have old ones for a pattern? Make a cardboard pattern of the windows, a few good photos of the windows and curtain rods, amd measurements of major landmarks in the photos.Or you could go to the fabric store get a nice print and have your wife, girlfriend or both help make the curtains. Gets her involved too and helps prevent "spinisterkers", those significant others left behind at dock.Mike
