WHAT ONE COSTS
$71,700est. used (2025, 1 yr old)

Sticker was $99,523 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
~13,518 lbestimated as towed, for 2 people

dry weight 12,168 lb + fresh water (66 gal, full) 550 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 around15,020 lb (10% margin)
GVWR (the sticker maximum)15,500 lb
Tongue weight, loaded~2,705 lb (20%)
Cargo capacity3,332 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 322RL's published weights held steady. Fifth wheels also need a pickup bed and are held to the fifth-wheel rating where published.
