WHAT ONE COSTS
—price not published

The maker never published an MSRP for this floorplan. Unknown is not cheap — treat any asking price against comparable models, not against zero.

WHAT IT WEIGHS BEHIND YOUR TRUCK
~11,752 lbestimated as towed, for 2 people

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.

You want a tow rating around13,060 lb (10% margin)
GVWR (the sticker maximum)13,000 lb
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.

THE READ
