It does have the storage under the bed that lifts up on gas struts. it also has a storage box under the floor that can be accessed from the tail gate when it closed. The storage box fits my stove, BBQ and tools. Its a really neat design. Also has storage areas along the bed on each side. I will start a thread in a few weeks with more pictures and the plans I have for it. I don't want to muddy yours up with my trailer. I will be watching your build. Is your a twin bed or a queen? The kamparoo is what started me down this road!
