WHAT ONE COSTS
$95,900est. used (2024, 2 yr old)

WHAT IT WEIGHS BEHIND YOUR TRUCK
~17,536 lbestimated as towed, for 2 people

dry weight 15,952 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.

GVWR (the sticker maximum)20,000 lb
Tongue weight, loaded~3,804 lb (22%)
Cargo capacity4,048 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 420's published weights held steady. Fifth wheels also need a pickup bed and are held to the fifth-wheel rating where published.
