WHAT IT WEIGHS BEHIND YOUR TRUCK

dry weight 12,135 lb + fresh water (75 gal, full) 626 lb + propane + battery 200 lb + gear for 2 600 lb. Brochure dry weight omits water, propane, batteries and your gear; this estimate doesn't.

GVWR (the sticker maximum)14,000 lb
Tongue weight, loaded~2,883 lb (21%)
Cargo capacity1,865 lb
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 3570LFT's published weights changed mid-run. Fifth wheels also need a pickup bed and are held to the fifth-wheel rating where published.
