dry weight 14,339 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.

GVWR (the sticker maximum)16,480 lb
Tongue weight, loaded~2,727 lb (17%)
Cargo capacity2,141 lb
WHICH TOW VEHICLES IT FITS: 18 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 377DS's published weights held steady. Fifth wheels also need a pickup bed and are held to the fifth-wheel rating where published.

FINDING ONE

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

OUR TAKE

New for 2026 - the only Columbus with a dual-suite/loft bedroom instead of a king. Replaces the 2024-25 376DS.
