This is pure speculation on my part. I owned a 2004 Bigfoot trailer. The build sheet showed the trailer weight to be 500+ pounds more than the brochure weight. Everything was considered an option including the entrance step, double pane windows and on an on. They listed the weight of each item, even added 1.2 pounds for a bedspread. Could be they changed their marketing and added everything into the brochure weight and reducing the number of options. Can't see them skimping on the fiberglass shell. Excellent product.
