Organizing shelf: For everyone who asked, this is my trailer and the shelving we installed. We used one 6ft long linen shelf with two Rubbermaid twin track and two track brackets. The twin tracks have a 3/4 depth. We used 1 3/4 wood screw; we placed the tracks where we found bracing/studs in the trailer wall. It was a great project very simple. All the products were purchased at Home Depot. Good luck have fun!!!
