WHAT ONE COSTS

$78,400est. used (2024, 2 yr old)

Sticker was $118,192 in 2024. Out of production since 2024, so the used market is the only way to buy one. Estimate assumes a 2024 unit.

WHAT IT WEIGHS BEHIND YOUR TRUCK

~15,530 lbestimated as towed, for 2 people

dry weight 14,054 lb + fresh water (81 gal, full) 676 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 around17,260 lb (10% margin)

GVWR (the sticker maximum)16,800 lb

Tongue weight, loaded~2,855 lb (18%)

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 3950BH's published weights held steady. Fifth wheels also need a pickup bed and are held to the fifth-wheel rating where published.
