The lower front bunk area has a mattress that folds up against the wall to allow storage of bikes and other large items in this space. We don't carry bikes, and my daughter does not like the mattress on the floor, so I added a light weight platform using 1x4 lumber and also added two storage drawers for clothing. The mattress still folds up out of the way to allow for larger items to be carried here. we still have access thru the large cargo door.
