WHAT ONE COSTS
$61,500est. used (2024, 2 yr old)

Sticker was $81,434 in 2024 — out of production since 2024, so the used market is the only way to buy one. Estimate assumes a 2024 unit.

WHAT IT WEIGHS BEHIND YOUR TRUCK
~12,350 lbestimated as towed, for 2 people

dry weight 11,108 lb + fresh water (53 gal, full) 442 lb + propane + battery 200 lb + gear for 2 600 lb. Brochure dry weight omits water, propane, batteries and your gear; this estimate doesn't.

You want a tow rating around13,725 lb (10% margin)
GVWR (the sticker maximum)13,250 lb
Tongue weight, loaded~1,573 lb (13%)
Cargo capacity2,142 lb
WHICH TOW VEHICLES IT FITS — 20 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 401FKSS's published weights held steady.
