WHAT IT WEIGHS BEHIND YOUR TRUCK
~21,451 lbestimated as towed, for 2 people

dry weight 19,400 lb + fresh water (150 gal, full) 1,251 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 around23,835 lb (10% margin)
GVWR (the sticker maximum)23,500 lb
Tongue weight, loaded~3,981 lb (19%)
WHICH TOW VEHICLES IT FITS: 8 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 4150's published weights held steady. Fifth wheels also need a pickup bed and are held to the fifth-wheel rating where published.
