The original 1500 series Bigfoot
(17 ft) has the dry bathroom (no shower) is the rear, street-side corner. As you move forward on the street-side, there is the closet with furnace
underneath; then the 3 burner cooktop; sink with converter underneath; then the frig. These models can be spotted easily by the presents of two (2'x 1.5') rear windows
. I haven't seen a drawing of this floorplan.
Later model 1500 series have a wet bathroom (with shower) in the rear, street-side corner. The closet has moved to the center, rear wall and the gaucho bed is narrower. These models have a single (2' x 1.5') rear window on the curb side. This floorplan is very similar to the 2500G series drawing.
