Most of the loss lands early: the Thor Motor Coach 23U GM 3500 sheds about 13% of its value in year one alone. From roughly $108,000 it falls to around $51,408 by year five — a five-year loss near $56,592, about $31.01 a day in depreciation.
Because the steepest drop hits around year 2, a lightly-used Thor Motor Coach 23U GM 3500 bought at 2 years old lets the first owner absorb the worst of the depreciation while the curve flattens — usually the value sweet spot.
