WHAT IT WEIGHS BEHIND YOUR TRUCK
~17,192 lbestimated as towed, for 2 people
dry weight 15,700 lb + fresh water (83 gal, full) 692 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 around19,105 lb (10% margin)
GVWR (the sticker maximum)19,000 lb
Tongue weight, loaded~3,603 lb (21%)
WHICH TOW VEHICLES IT FITS: 14 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 417KB's published weights changed mid-run. Fifth wheels also need a pickup bed and are held to the fifth-wheel rating where published.
