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
~16,319 lbestimated as towed, for 2 people

dry weight 15,044 lb + fresh water (57 gal, full) 475 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 around18,135 lb (10% margin)
GVWR (the sticker maximum)17,995 lb
Tongue weight, loaded~3,070 lb (19%)
Cargo capacity2,951 lb
WHICH TOW VEHICLES IT FITS — 15 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 ROOST43'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
  • 2025Introduced as the line flagship
FINDING ONE

Findable — a few listed nationwide most weeks. Why: Forest River is a volume manufacturer; only 2 model years; still in production. Estimated from build volume and production span — not a count of live listings.

THE READ

530 sq ft flagship with triple 15,000 BTU A/C and 6'8" clearance in every room; needs a serious truck.
