WHAT ONE COSTS
$42,800est. used (2018, 8 yr old)

WHAT IT WEIGHS BEHIND YOUR TRUCK
~14,182 lbestimated as towed, for 2 people

dry weight 12,465 lb + fresh water (110 gal, full) 917 lb + propane + battery 200 lb + gear for 2 600 lb. Brochure dry weight omits water, propane, batteries and your gear; this estimate doesn't.

Tongue weight, loaded~3,226 lb (23%)
Cargo capacity4,370 lb
WHICH TOW VEHICLES IT FITS: 19 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 341's published weights changed mid-run. Fifth wheels also need a pickup bed and are held to the fifth-wheel rating where published.
