The interior vertical wood trim on our M21 slide has loosened at the bottom of the trim piece. We're presently at the Bath, NY rally and the local Heartland dealer said that these strips are stapled on. However, I cannot find any staples and want to reattach without the hassle and time to bring to my dealer. My local dealer is 40 miles away from my home and took 2.5 weeks to replace the bath fan, so I'm in no hurry to bring it back to them. How do I reattach this vertical wood trim?
