I'm getting close to finishing this up and thought should share. I'm going to hard line the propane feed through an tubular burner stand and make a fold down shelf/table on the tire swing to hold the propane and a Jerry can of water.
This drawer system is built in a US military mortar can that are made to stack horizontally. I plan to have the burner drawer on the bottom with two more cans with drawers stacked on top for storage of dry goods, pans, utensils, and whatever else is needed for extended trips. It was a very very tight fit but I'm extremely happy with how it turned out.
