WHAT IT WEIGHS BEHIND YOUR TRUCK
~9,900 lbestimated as towed, for 2 people

dry weight 8,840 lb + fresh water (45 gal, full) 375 lb + propane + battery 200 lb + gear for 2 600 lb — capped at its own rating. Brochure dry weight omits water, propane, batteries and your gear; this estimate doesn't.

You want a tow rating around11,000 lb (10% margin)
GVWR (the sticker maximum)9,900 lb
Tongue weight, loaded~874 lb (9% — low, watch for sway)
Cargo capacity1,028 lb
WHICH TOW VEHICLES IT FITS — 33 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 3375KL's published weights held steady.
