Most of the loss lands early: the Flagstaff By Forest River 21SSL sheds about 12% of its value in year one alone. From roughly $48,044 it falls to around $29,643 by year five — a five-year loss near $18,401, about $10.08 a day in depreciation.
Because the steepest drop hits around year 1, a lightly-used Flagstaff By Forest River 21SSL bought at 1 year old lets the first owner absorb the worst of the depreciation while the curve flattens — usually the value sweet spot.
