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
~6,492 lbestimated as towed, for 2 people

dry weight 5,358 lb + fresh water (40 gal, full) 334 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 around7,215 lb (10% margin)
GVWR (the sticker maximum)6,858 lb
Tongue weight, loaded~709 lb (11%)
Cargo capacity1,500 lb
WHICH TOW VEHICLES IT FITS — 60 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 20MKB's published weights held steady.

FINDING ONE

Findable — a few listed nationwide most weeks. Why: Forest River 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

New for 2026; only Beast Mode weights were published at print, standard package still TBD.
