I had a fabric accordion door in mine. Bought a 28" HC flat panel door form the big box. I had to trim the door and frame, ditch the molding and make it fit. It takes a slow hand; measure carefully and use lots of screws. I stained it something close to the rest of the wood. Only other trick is I have to jam something between the top of the door and frame when on the road. There is just not enough wood left to support everything when it's bouncing down the road. 2 years later and it's still there and the latch works fine.
