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
~12,592 lbestimated as towed, for 2 people

dry weight 11,475 lb + fresh water (38 gal, full) 317 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 around13,995 lb (10% margin)
GVWR (the sticker maximum)13,000 lb
Tongue weight, loaded~1,657 lb (13%)
Cargo capacity1,525 lb
WHICH TOW VEHICLES IT FITS — 20 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 40FBTS'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.
