WHAT ONE COSTS
$54,200est. used (2024, 2 yr old)

Sticker was $81,735 in 2024. Out of production since 2024, so the used market is the only way to buy one. Estimate assumes a 2024 unit.

WHAT IT WEIGHS BEHIND YOUR TRUCK

dry weight 10,510 lb + fresh water (53 gal, full) 442 lb + propane + battery 200 lb + gear for 2 600 lb. Brochure dry weight omits water, propane, batteries and your gear; this estimate doesn't.

Tongue weight, loaded~1,789 lb (15%: high, eats payload)
Cargo capacity2,490 lb
WHICH TOW VEHICLES IT FITS: 23 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 40FKDS's published weights changed mid-run.

FINDING ONE

Common: usually several for sale within a day’s drive. Why: Jayco is a volume manufacturer; 10-year production run. Estimated from build volume and production span, not a count of live listings.

OUR TAKE

The long-running front-kitchen couples plan — nine model years, the biggest grey capacity in the line and no bunks anywhere.
