WHAT ONE COSTS
—price not published

The maker never published an MSRP for this floorplan. Unknown is not cheap — treat any asking price against comparable models, not against zero.

WHAT IT WEIGHS BEHIND YOUR TRUCK
~13,413 lbestimated as towed, for 2 people

dry weight 12,129 lb + fresh water (58 gal, full) 484 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 around14,905 lb (10% margin)
GVWR (the sticker maximum)15,500 lb
Tongue weight, loaded~2,895 lb (22%)
Cargo capacity3,371 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 RF36SB's published weights held steady. Fifth wheels also need a pickup bed and are held to the fifth-wheel rating where published.

CrossRoads (Mixed tier): CrossRoads' short-lived luxury fifth wheel, built 2011-2016 first under DS Corp and then Keystone - aluminum-framed laminated walls, 12 in I-beam and 7,000 lb axles were competitive, but the line changed floorplan naming twice in six years and vanished, so parts and resale support are thin.

FINDING ONE

Findable — a few listed nationwide most weeks. Why: CrossRoads is a volume manufacturer; 13 years out of production. Estimated from build volume and production span — not a count of live listings.

THE READ

Side-bath 39-footer - three slides, so lighter than the four-slide plans at the same length.
