Sportsmobile R 138P Promaster keeps an estimated 68% of its value after 5 years — #961 of 5706 RVs & trailers VINdown tracks.
Per VINdown's modeling, the Sportsmobile R 138P Promaster retains an estimated 68% of its value after five years, ranking #961 of 5706 RVs & trailers we track. That is roughly in line with the 69% five-year average for Class B in its class.
Most of the loss lands early: the Sportsmobile R 138P Promaster sheds about 17% of its value in year one alone. From roughly $136,272 it falls to around $93,210 by year five — a five-year loss near $43,062, about $23.60 a day in depreciation.
Because the steepest drop hits around year 1, a lightly-used Sportsmobile R 138P Promaster bought at 1 year old lets the first owner absorb the worst of the depreciation while the curve flattens — usually the value sweet spot.
