WHAT ONE COSTS
$42,400est. used (2020, 6 yr old)

WHAT IT WEIGHS BEHIND YOUR TRUCK
~13,192 lbestimated as towed, for 2 people

dry weight 11,892 lb + fresh water (60 gal, full) 500 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 around14,660 lb (10% margin)
GVWR (the sticker maximum)15,500 lb
Tongue weight, loaded~2,411 lb (18%)
WHICH TOW VEHICLES IT FITS: 19 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 368FBDS's published weights held steady. Fifth wheels also need a pickup bed and are held to the fifth-wheel rating where published.
