WHAT ONE COSTS
$72,900est. used (2025, 1 yr old)

Sticker was $101,318 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
~13,673 lbestimated as towed, for 2 people

dry weight 12,456 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.

Tongue weight, loaded~2,451 lb (18%)
Cargo capacity2,496 lb
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 386BH's published weights changed mid-run. Fifth wheels also need a pickup bed and are held to the fifth-wheel rating where published.
