Per VINdown's modeling, the Gulf Stream 21TBD retains an estimated 41% of its value after five years, ranking #5643 of 5948 RVs & trailers we track. That trails the 55% five-year average for Travel Trailer in its class by 14 points, so it depreciates faster than most rivals.
Most of the loss lands early: the Gulf Stream 21TBD sheds about 41% of its value in year one alone. From roughly $44,822 it falls to around $18,242 by year five — a five-year loss near $26,580, about $14.56 a day in depreciation.
Because the steepest drop hits around year 1, a lightly-used Gulf Stream 21TBD bought at 1 year old lets the first owner absorb the worst of the depreciation while the curve flattens — usually the value sweet spot.
