Some of the 300 lbs may have been due to elimination of two windows (front and back), the "tin" front window shield, and a sink. Also the tall cabinet storage left of the reefer, and small closet in rear of travel trailer were eliminated.
In return, the front seating area was expanded and a larger table. A further change was an increase in size of the top bunk with more head room.
