While taking down "Minion" from his first tour of duty, my wife noticed the left curved bed rail came out of the ply due to rot. We got him home and reopened for closer inspection. All 4 curved bracket ends are pulling out of the ply on both bunks. The bunks also sag in the middle and scrape the top of the box during setup or take down. Decided to replace one end this weekend and tackle the other side another weekend. Ours has rivets. Lots of rivets. Took a while to get them all drilled out, mark location of everything on bunk end with a sharpie, and remove stops. Our original ply was .5 inch so went with 19/32 with plan to sand / hammer the aluminium edge shaped like a "C" to reinstall. Our bunks are queen, so i had to lay 2 pieces of 4x8 side by side and draw shape of original, then use PL400 to join them. Over seam i used underlayment wood (local orange box didnt stock launa). Will update thread as it comes together. Thought it would be helpful to others to have a step by step for this project. I looked at 10+ threads and then formulated my plan.
