WHAT ONE COSTS
—price not published

The maker never published an MSRP for this floorplan. Unknown is not cheap — treat any asking price against comparable models, not against zero.

WHAT IT WEIGHS BEHIND YOUR TRUCK
~17,201 lbestimated as towed, for 2 people

dry weight 15,150 lb + fresh water (150 gal, full) 1,251 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 around19,115 lb (10% margin)
GVWR (the sticker maximum)18,000 lb
Tongue weight, loaded~3,600 lb (21%)
Cargo capacity2,850 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 421FL's published weights changed mid-run. Fifth wheels also need a pickup bed and are held to the fifth-wheel rating where published.
