WHAT ONE COSTS
$52,500est. used (2021, 5 yr old)

Sticker was $79,515 in 2018. Out of production since 2021, so the used market is the only way to buy one. Estimate assumes a 2021 unit.

WHAT IT WEIGHS BEHIND YOUR TRUCK
~12,239 lbestimated as towed, for 2 people

dry weight 10,880 lb + fresh water (67 gal, full) 559 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 around13,600 lb (10% margin)
GVWR (the sticker maximum)14,067 lb
Tongue weight, loaded~2,325 lb (19%)
Cargo capacity3,187 lb
WHICH TOW VEHICLES IT FITS: 20 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 33IK's published weights changed mid-run. Fifth wheels also need a pickup bed and are held to the fifth-wheel rating where published.
