Our Heartland Bighorn fifth-wheel had a rough edge on the bed platform. I found that drywall J-channel trim fit the edge of the ½-inch oriented strand board (OSB) base perfectly. I cut the pieces to fit, and the platform now has smooth, finished edges. I bought the J-channel in 10-foot lengths for $2.40 at Home Depot.
