Abstract: A travel trailer having a two-level chassis supporting at least two discrete floor sections at at least two different heights above the ground with at least one of those floors having a bathroom portion being supported by an upper chassis beam is disclosed. In a preferred embodiment, the chassis has a substantially horizontal forward upper portion and a substantially horizontal rearward lower portion, and an upper floor is secured to the upper portion and a lower floor is secured to the lower portion with an intermediate floor positioned below the upper edge of the upper portion of the chassis to a height intermediate that of the upper and lower floors. In an alternative preferred embodiment, the intermediate floor is suspended below the upper chassis portion. The area underneath the intermediate section and above the bottom of the trailer defines a storage area that is not blocked or limited in size by the width of the chassis beams.
