Keystone RV 3660 RL keeps an estimated 45% of its value after 5 years — #5142 of 5706 RVs & trailers VINdown tracks. See the full depreciation curve.
Per VINdown's modeling, the Keystone RV 3660 RL retains an estimated 45% of its value after five years, ranking #5142 of 5706 RVs & trailers we track. That trails the 55% five-year average for Travel Trailer in its class by 10 points, so it depreciates faster than most rivals.
Most of the loss lands early: the Keystone RV 3660 RL sheds about 14% of its value in year one alone. From roughly $78,917 it falls to around $35,433 by year five — a five-year loss near $43,484, about $23.83 a day in depreciation.
Because the steepest drop hits around year 4, a lightly-used Keystone RV 3660 RL bought at 4 years old lets the first owner absorb the worst of the depreciation while the curve flattens — usually the value sweet spot.

It keeps an estimated 45% of its value after five years — worse than most among the 5706 RVs & trailers VINdown tracks (ranked #5142).
From about $78,917 when new it drops to roughly $35,433 after five years — a loss near $43,484 (45% of its value retained).
Around 4 years old: that is just past the steepest depreciation, so you skip the biggest drop while the value curve is flattening.
