dry weight 10,160 lb + fresh water (76 gal, full) 634 lb + propane + battery 200 lb + gear for 2 600 lb. Brochure dry weight omits water, propane, batteries and your gear; this estimate doesn't.

GVWR (the sticker maximum)12,995 lb
Tongue weight, loaded~2,135 lb (18%)
Cargo capacity2,835 lb
WHICH TOW VEHICLES IT FITS: 22 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 31RL's published weights changed mid-run. Fifth wheels also need a pickup bed and are held to the fifth-wheel rating where published.

UnderbellyEnclosed

KZ (Mixed tier): Ridgeway is KZ's newest fifth wheel (Thor Industries), launched for 2025 to sit above Durango. The spec sheet is genuinely upper-tier — aluminum-framed laminated sidewalls over Azdel composite on a powder-coated steel I-beam chassis, a walk-on Tufflex PVC roof with a lifetime warranty, heated and enclosed underbelly with in-floor heated PEX, dual 13.5K A/Cs standard and KZ's two-year hitch-to-bumper warranty. It is too new to have an owner track record, and KZ's history of uneven assembly is the reason it sits in the middle rather than at the top.
