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
~11,952 lbestimated as towed, for 2 people

dry weight 10,710 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 around13,280 lb (10% margin)
GVWR (the sticker maximum)13,200 lb
Tongue weight, loaded~1,401 lb (12%)
Cargo capacity2,490 lb
WHICH TOW VEHICLES IT FITS — 22 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 39FDEN's published weights held steady.
