WHAT ONE COSTS
$35,000est. used (2013, 13 yr old)

WHAT IT WEIGHS BEHIND YOUR TRUCK
~13,790 lbestimated as towed, for 2 people

dry weight 12,506 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.

Tongue weight, loaded~2,724 lb (20%)
Cargo capacity3,444 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 RF39SB's published weights held steady. Fifth wheels also need a pickup bed and are held to the fifth-wheel rating where published.

UnderbellyEnclosed

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.

YEAR BY YEAR: WHAT CHANGED
  • 2012Introduced at a 15,950 lb GVWR, the highest of the RF generation
  • 2013Final year
FINDING ONE

Findable: a few listed nationwide most weeks. Why: CrossRoads is a volume manufacturer; only 2 model years; 13 years out of production. Estimated from build volume and production span, not a count of live listings.

OUR TAKE

The only RF plan rated over 15,500 lb - a 40 ft side-bath coach with a bit more headroom on weight.
