Hard to tell from the catalog what that looks like. Is it a corner edge of the divider that separates the sleeping area from the rest of the trailer? If it's wood, you could try using a foam sanding block and rounding it a bit, then dabbing a little stain on it. Or you could check at a home center (Lowes, Home Depot) for a plastic corner molding that would give it a rounded edge and glue that over the sharp area. A photo would help.
