dry weight 17,540 lb + fresh water (173 gal, full) 1,443 lb + propane + battery 200 lb + gear for 2 600 lb. Brochure dry weight omits water, propane, batteries and your gear; this estimate doesn't.

WHICH TOW VEHICLES IT FITS: 12 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 432's published weights held steady. Fifth wheels also need a pickup bed and are held to the fifth-wheel rating where published.
