—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
~19,888 lbestimated as towed, for 2 people

dry weight 17,645 lb + fresh water (173 gal, full) 1,443 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 around22,100 lb (10% margin)
GVWR (the sticker maximum)21,000 lb
Tongue weight, loaded~4,497 lb (23%)
Cargo capacity3,355 lb
WHICH TOW VEHICLES IT FITS — 12 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 433's published weights held steady. Fifth wheels also need a pickup bed and are held to the fifth-wheel rating where published.

YEAR BY YEAR — WHAT CHANGED

FINDING ONE

Findable — a few listed nationwide most weeks. Why: Keystone is a volume manufacturer; only one model year; still in production. Estimated from build volume and production span — not a count of live listings.

THE READ

Two full bathrooms and a large master suite behind a 13'6" garage - the heaviest Raptor built.
