I can sew and found some hints for tailoring bedsheets on this forum, but haven't had much luck in the past.
We took a recommendation from the forum and ordered custom-made waterproof mattress covers and sheets for our 2552 (with two long beds) from ABLifestyles in South Carolina. They specialize in making bedding and accessories for campers and RVs. We looked online, ordered on the phone and received the sheets one week later. Cost for two beds worth of mattress pad, fitted sheet, flat sheet, and pillow case was $280. We just ordered our PC, so haven't slept on them yet, but they feel good.
If you want to give them a try: ablifestyles.net, 800-825-4533. They are located in Iva, SC.
