As I will not be using the "upper bed" area as a bed I had the dealer remove the mattress and put it on one of the beds in the garage, then I purchased a bunch of 5 gallon tubs and store items in them up there. I installed a extra peice of wood along the front rail to stop the tuds from crasing forward I labled everything with duct tape. I also use "Space bags" under the bed and for the bottom of the closet below the hanging clothes.
