The Palm Harbor / The Secret Cove HD28603C built by Cavco Millersburg is a 3-bedroom, 2-bathroom multi-section home with 1,620 square feet on a 60-foot frame. It’s one of four identical-spec Palm Harbor models sharing this exact 1,620-square-foot, 60×27 footprint, alongside the Deschutes, Mary’s Peak, and Willow Home. That same spec also appears cross-series on the 400 Series’ Truman I and Klamath IV, and the American Dream Series’ Mt. Anderson. It’s part of the densest identical-spec cluster at this factory.
