WHAT ONE COSTS

$74,900est. used (2025, 1 yr old)

Sticker was $104,027 in 2025. Out of production since 2025, so the used market is the only way to buy one. Estimate assumes a 2025 unit.

WHAT IT WEIGHS BEHIND YOUR TRUCK

~14,816 lbestimated as towed, for 2 people

dry weight 13,599 lb + fresh water (50 gal, full) 417 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 around16,465 lb (10% margin)

GVWR (the sticker maximum)16,260 lb

Tongue weight, loaded~2,462 lb (17%)

WHICH TOW VEHICLES IT FITS: 19 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 3880BH's published weights changed mid-run. Fifth wheels also need a pickup bed and are held to the fifth-wheel rating where published.
