WHAT ONE COSTS
$35,500est. used (2025, 1 yr old)

Sticker was $46,844 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
~8,122 lbestimated as towed, for 2 people

dry weight 6,980 lb + fresh water (41 gal, full) 342 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 around9,025 lb (10% margin)
GVWR (the sticker maximum)9,608 lb
Tongue weight, loaded~940 lb (12%)
Cargo capacity2,596 lb
WHICH TOW VEHICLES IT FITS — 43 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 31DB's published weights changed mid-run.
