The Sapphire Series / 16763B built by Cavco Dorchester is a 3-bedroom, 2-bathroom single-section home with 1,140 square feet on a 76-foot frame. It shares its 1,140-square-foot total, 76-foot length, and 15-foot width with the 2-bedroom 16762A and 16762B, fitting a third bedroom into the identical footprint. It's also a near-twin of the 16763A, which carries the same bed and bath count and square footage but is built 1 foot wider at 16 feet. It's one of the series' 3-bedroom single-section options.
