dry weight 15,645 lb + fresh water (75 gal, full) 626 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 around18,970 lb (10% margin)
GVWR (the sticker maximum)17,995 lb
Tongue weight, loaded~3,372 lb (20%)
Cargo capacity2,350 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 39FL's published weights held steady. Fifth wheels also need a pickup bed and are held to the fifth-wheel rating where published.

Heartland (Mixed tier): Bighorn

YEAR BY YEAR — WHAT CHANGED
  • 2026Introduced (successor to the 3950FL)
FINDING ONE

Findable — a few listed nationwide most weeks. Why: Heartland 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
