We just bought a Winnebago Winnie 2201DS because of the storage space and outside kitchen. Winnebago is also manufacturing "kissing cousins" in their Sunnybrook Remington line. Check out Winnebago floorplans at:

If you look at the 2201DS, you'll see the double wardrobe and other storage area in the bathroom. The unit also has a decent size pantry, and adequate storage in the galley. There is also storage under the entire dinette seating, and a pass thru storage area at the front of the unit. It was the most storage we could find in a trailer under 27' total length aside from a Lance model which is almost impossible to find anwhere east of the Mississippi...or at least too far from us in the Cleveland, OH area.
