Tom;
When I was stationed in South Dakota and lived in Military Family Housing, space was also at a premium!
I sacrificed the hallway closet and built a bench with a 22 in X 4 ft top, made out of 2 pieces of 3/4 inch plywood laminated together and it just fit inside this closet! The closet had sliding doors and when I wanted to reload, I simply lifted the doors off and pulled up a chair and started reloading! Not only was it convenient, but when not in use, it was out of sight!
I still use that bench today!
