2026 Forest River Sabre36FLX

The 36FLX is Sabre’s most versatile plan, and the one built for work and a crowd. The “FLX” marks a Flex Room that doubles as a mobile office or extra sleeping space, with a large loft overhead for storage or sleeping, bunk beds, an island kitchen with a free-standing dinette option and a hidden pantry, an outside kitchen, a fireplace, a sleeper sofa and a rear living area with oversized windows. Four slide-outs open it up and it sleeps up to ten. It rides the full Sabre build: the Lippert M-19 welded I-beam chassis, vacuum-bond laminated sidewalls, a high-gloss gelcoat front cap and an electric auto-level system.

Forest River publishes a 12,503-pound UVW and a 2,800-pound CCC, which derive a 15,303-pound GVWR (the manufacturer’s own definition is that CCC equals GVWR minus UVW), against a 2,350-pound dry pin. Twin 15,000-BTU ducted air conditioners (prepped for a third), a tankless water heater, a 12-volt refrigerator, real wood lumbercore cabinetry, solid-surface countertops, smart projectors in the primary bedroom and a tri-fold sleeper sofa are standard, under dual 10-foot-8-inch and 21-foot awnings — the longest awning span in the line.

US street pricing has run around the low $60,000s (units have advertised near $60,800). It is the work-and-play, big-family Sabre. For a family that wants a flexible mobile office that converts to sleeping, a loft, bunk beds, an outside kitchen and a rear living area in an affordable-luxury full-size fifth wheel — towed behind a properly rated three-quarter-ton or larger truck — the 36FLX is the line’s most versatile plan.

Sabre is Forest River's affordable-luxury full-size fifth wheel — a half-step above the brand's own up-trim sibling Sandpiper toward the Cedar Creek luxury line, and a cross-shop against Grand Design's Reflection and Keystone's Cougar from just above. Six of the most distinct 2026 retail floorplans are profiled here in full. The 36FLX on this page is highlighted; each other plan links to its own page.
