Here’s another way to get organized while camping—use some of the plastic drawer units available from places like Wal-Mart to store dry food in.
While driving, these get pushed to the front of the trailer, and the tent/chuckbox gets packed in the rear. The only challenge with this arrangement is if you need to get into the drawers before setting up camp or after breaking camp.
Note that I had to buy both of these in the 3-drawer versions and remove one drawer. Cost was about $35.
