WHAT ONE COSTS
$24,600est. used (2015, 11 yr old)

Sticker was $46,555 in 2012. Out of production since 2015, so the used market is the only way to buy one. Estimate assumes a 2015 unit.

WHAT IT WEIGHS BEHIND YOUR TRUCK
~11,012 lbestimated as towed, for 2 people

dry weight 9,678 lb + fresh water (64 gal, full) 534 lb + propane + battery 200 lb + gear for 2 600 lb. Brochure dry weight omits water, propane, batteries and your gear; this estimate doesn't.

You want a tow rating around12,240 lb (10% margin)
GVWR (the sticker maximum)14,185 lb
Tongue weight, loaded~2,486 lb (23%)
Cargo capacity4,507 lb
WHICH TOW VEHICLES IT FITS: 28 OF 95

Judged the way the app judges: estimated loaded weight against each vehicle's rating less a 10% margin, per model year, because the 285RLD's published weights changed mid-run. Fifth wheels also need a pickup bed and are held to the fifth-wheel rating where published.

FINDING ONE

Common: usually several for sale within a day’s drive. Why: Keystone is a volume manufacturer; 8-year production run; 11 years out of production. Estimated from build volume and production span, not a count of live listings.

OUR TAKE

Shortest and lightest Mountaineer fifth wheel, and the longest-running plan in the line. 4,507 lb of cargo is exceptional for a 32-footer.
