WHAT ONE COSTS
$25,200est. used (2014, 12 yr old)

Sticker was $51,155 in 2013. Out of production since 2014, so the used market is the only way to buy one. Estimate assumes a 2014 unit.

WHAT IT WEIGHS BEHIND YOUR TRUCK
~11,473 lbestimated as towed, for 2 people

dry weight 10,139 lb + fresh water (64 gal, full) 534 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 around12,750 lb (10% margin)
GVWR (the sticker maximum)14,045 lb
Tongue weight, loaded~2,314 lb (20%)
Cargo capacity3,906 lb
WHICH TOW VEHICLES IT FITS: 21 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 290RLT's published weights held steady. Fifth wheels also need a pickup bed and are held to the fifth-wheel rating where published.
