WHAT ONE COSTS
$96,900est. used (2021, 5 yr old)

Sticker was $151,507 in 2020. Out of production since 2021, so the used market is the only way to buy one. Estimate assumes a 2021 unit.

WHAT IT WEIGHS BEHIND YOUR TRUCK
~16,883 lbestimated as towed, for 2 people

dry weight 15,416 lb + fresh water (80 gal, full) 667 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 around18,760 lb (10% margin)
GVWR (the sticker maximum)18,000 lb
Tongue weight, loaded~3,738 lb (22%)
Cargo capacity2,532 lb
WHICH TOW VEHICLES IT FITS: 14 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 Phoenix's published weights changed mid-run. Fifth wheels also need a pickup bed and are held to the fifth-wheel rating where published.
