WHAT ONE COSTS
$106,000est. used (2025, 1 yr old)

Sticker was $144,295 in 2024. Out of production since 2025, so the used market is the only way to buy one. Estimate assumes a 2025 unit.

WHAT IT WEIGHS BEHIND YOUR TRUCK
~18,229 lbestimated as towed, for 2 people

dry weight 16,645 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.

Tongue weight, loaded~4,019 lb (22%)

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 431's published weights changed mid-run. Fifth wheels also need a pickup bed and are held to the fifth-wheel rating where published.
