The SL models (like mine) have storage space under the couch that is assessible only from outside (unless you lift the couch cushion, which is kind of a pain). True, it is not below the floor - but is this a basement? Similarly, there is a compartment under the rear bed that is accessible only from the outside. Half the width of the TM, about 36" high, and about 18" front-to-back. This is where I keep water hoses / filters / connectors adapters, heavy duty extension cords, TV cable, tools, etc.
