Keystone Fuzion 379
Sticker was $134,543 in 2024. Out of production since 2024, so the used market is the only way to buy one. Estimate assumes a 2024 unit.
dry weight 14,730 lb + fresh water (94 gal, full) 784 lb + propane + battery 200 lb + gear for 2 600 lb. Brochure dry weight omits water, propane, batteries and your gear; this estimate doesn't.
Judged the way the app judges: estimated loaded weight against each vehicle's rating less a 10% margin, per model year, because the 379's published weights held steady. Fifth wheels also need a pickup bed and are held to the fifth-wheel rating where published.
