dry weight 15,160 lb + fresh water (110 gal, full) 917 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~4,108 lb (24%)
Cargo capacity3,840 lb
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 398TS's published weights held steady. Fifth wheels also need a pickup bed and are held to the fifth-wheel rating where published.
