What a great idea!! I found a couple of "under the bed" storage boxes that we shove under there. They are the length of a fill size bed - lids and all. One holds extra "weather" clothes and the other holds all dry goods for cooking - beans, rice, cereal, pasta - everything. They slide out easily and you can see everything you've got at a glance

instead of digging under the bed. Plus - you can load them in the house!!

They also stay in place
Also, as an afterthought - We were shopping in Santa Fe and had a couple of pretty nice things that I didn't want to worry about. We slide our under-the-bed boxes out which leaves us a cabinet door to the side bins behind the wheels. We had a couple of those canvas and wire baskets that we loaded up with treasures and could shotput in there, close the cabinet door and replace the storage boxes. The bins kept the items padded and from falling over. Since you have to squeeze under the bed to get all this accomplished, I would have felt comfortable with gold bricks back there!!

ONE MORE - since our bed is queen, we have a little space in front of the storage boxes. We have some "kind of nice" dishes that I wanted to store there. We got a plastic legal size file box from WalMart and some file folders. The closed box is a nice tight fit. Each dish goes in a folder then in the box. Gives plenty of padding and is easier than wrapping everything every time. Before this, I never used the stuff because it was too hard to get it unwrapped and wrapped again
