WHAT IT WEIGHS BEHIND YOUR TRUCK
~12,517 lbestimated as towed, for 2 people
dry weight 11,100 lb + fresh water (74 gal, full) 617 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 around13,910 lb (10% margin)
GVWR (the sticker maximum)13,995 lb
Tongue weight, loaded~2,481 lb (20%)
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 320MKS's published weights held steady. Fifth wheels also need a pickup bed and are held to the fifth-wheel rating where published.
