Here's a bunk I made for my Tradewind. It works great and the grandkids fight over it. The fabric is canvas. The frame is aluminum tubing held together with portable exhibit display clamps. The outboard side attaches to the wall and the inboard side is supported from the ceiling by marine bimini top hardware and nylon webbing. It will support a good size child. It installs and stows in 5 minutes. It stows behind the gaucho invisibly. The idea is from the original Airstream bunk option. The hardest part of the project is to find solid anchor points in the wall and ceiling
