Per VINdown's modeling, the Bison 81515B S retains an estimated 76% of its value after five years, ranking #620 of 5948 RVs & trailers we track. That is 20 points above the 55% five-year average for Travel Trailer in its class, so it holds value better than most rivals.
Most of the loss lands early: the Bison 81515B S sheds about 16% of its value in year one alone. From roughly $88,536 it falls to around $66,933 by year five — a five-year loss near $21,603, about $11.84 a day in depreciation.
Because the steepest drop hits around year 2, a lightly-used Bison 81515B S bought at 2 years old lets the first owner absorb the worst of the depreciation while the curve flattens — usually the value sweet spot.
