WHAT ONE COSTS
$156,400est. used (2022, 4 yr old)

Sticker was $196,500 in 2022. Out of production since 2022, so the used market is the only way to buy one. Estimate assumes a 2022 unit.

WHAT IT WEIGHS BEHIND YOUR TRUCK
~9,625 lbestimated as towed, for 2 people

dry weight 8,375 lb + fresh water (54 gal, full) 450 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 around10,695 lb (10% margin)
GVWR (the sticker maximum)10,000 lb
Tongue weight, loaded~1,149 lb (12%)
Cargo capacity1,625 lb
WHICH TOW VEHICLES IT FITS: 34 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 33FB Twin's published weights changed mid-run.
