Had to add a metal washer to one of my pocket doors. I ended up taking off the modeling (on the bedroom side...). Slow and steady and the thin staples and/or nails came out pretty easy. I did re-nail the trim backup with my air nailer but if I had to do it again, I would use screws.
It's amazing how many items are installed with the cheapest of material. I get trying to save money and weight. I would rather pay extra $$$ and lose some cargo weight to have a better built trailer.
