dry weight 11,275 lb + fresh water (81 gal, full) 676 lb + propane + battery 200 lb + gear for 2 600 lb. Brochure dry weight omits water, propane, batteries and your gear; this estimate doesn't.

Tongue weight, loaded~2,658 lb (21%)
Cargo capacity2,725 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 3560RLB's published weights held steady. Fifth wheels also need a pickup bed and are held to the fifth-wheel rating where published.
