WHAT ONE COSTS
$37,600est. used (2018, 8 yr old)

WHAT IT WEIGHS BEHIND YOUR TRUCK
~13,062 lbestimated as towed, for 2 people

dry weight 11,636 lb + fresh water (75 gal, full) 626 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 around14,515 lb (10% margin)
GVWR (the sticker maximum)14,636 lb
Tongue weight, loaded~2,719 lb (21%)
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 320RS's published weights changed mid-run. Fifth wheels also need a pickup bed and are held to the fifth-wheel rating where published.
