butterfish, I learned a trick from another Hi Lo owner that you can remove the "wall paper" with a heat gun in the really bad areas, then use "TSP" from the depot. Mix according to directions. Wash the "paneling" down and rinse with fresh water, Wa-la, it's ready for paint. We brightened our 27'er up two shades of gray and gloss white trim. And it doesn't scrape off! This is AFTER you find and correct the leaking areas. With new fabrics, our unit no longer looks like a hunters cabin.
