WHAT IT WEIGHS BEHIND YOUR TRUCK
~12,992 lbestimated as towed, for 2 people

dry weight 11,566 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 around14,440 lb (10% margin)
GVWR (the sticker maximum)14,566 lb
Tongue weight, loaded~2,402 lb (18%)
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 340RK's published weights changed mid-run. Fifth wheels also need a pickup bed and are held to the fifth-wheel rating where published.
