WHAT ONE COSTS
$26,300est. used (2018, 8 yr old)

dry weight 10,235 lb + fresh water (48 gal, full) 400 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~1,816 lb (16%: high, eats payload)
Cargo capacity2,265 lb

Judged the way the app judges: estimated loaded weight against each vehicle's rating less a 10% margin, per model year, because the 40FSDS's published weights changed mid-run.

FINDING ONE

Findable: a few listed nationwide most weeks. Why: Jayco is a volume manufacturer. Estimated from build volume and production span, not a count of live listings.

OUR TAKE
