The Diamond Series / Sapphire 5863 built by Cavco Lake Arlington is a 3-bedroom, 2-bathroom singlewide with 1,330 square feet of living space on a 76-foot frame. Its 76-by-18 footprint matches the Tiffany J76K exactly, so buyers comparing the two are really choosing between two names on the same-size home. Both stand among the longer singlewides in the Diamond Series lineup.
