Fifth wheelbuilt 2012–17Mixed build tierFindable on the used market
WHAT ONE COSTS
$32,400est. used (2017, 9 yr old)

Sticker was $55,733 in 2015. Out of production since 2017, so the used market is the only way to buy one. Estimate assumes a 2017 unit.

WHAT IT WEIGHS BEHIND YOUR TRUCK
~14,292 lbestimated as towed, for 2 people

dry weight 13,100 lb + fresh water (47 gal, full) 392 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 around15,880 lb (10% margin)
GVWR (the sticker maximum)15,500 lb
Tongue weight, loaded~2,258 lb (16%)
Cargo capacity2,400 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 37 Ultimate's published weights held steady. Fifth wheels also need a pickup bed and are held to the fifth-wheel rating where published.
