WHAT ONE COSTS
$45,000est. used (2022, 4 yr old)

Sticker was $69,309 in 2021. Out of production since 2022, so the used market is the only way to buy one. Estimate assumes a 2022 unit.

WHAT IT WEIGHS BEHIND YOUR TRUCK
~12,726 lbestimated as towed, for 2 people

dry weight 11,376 lb + fresh water (66 gal, full) 550 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 around14,140 lb (10% margin)
GVWR (the sticker maximum)15,000 lb
Tongue weight, loaded~2,646 lb (21%)
Cargo capacity3,624 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 300RE's published weights changed mid-run. Fifth wheels also need a pickup bed and are held to the fifth-wheel rating where published.
