2026 Salem Hemisphere 308RL

The Salem Hemisphere 308RL is the most spacious Hemisphere built for couples — a triple-slide rear-living coach with a panoramic-window lounge across the back, a kitchen island, a front bedroom with a custom king bed, and, past the bedroom, a walk-in wardrobe and a washer/dryer area sized for a separate washer and dryer. It is the one Hemisphere plan without a front windshield, by design. Its twin in the Wildwood Heritage Glen 308RL is the identical trailer in different décor.

It carries the premium-laminate build of the line: a vacuum-laminated “Aluma Frame” sidewall and floor with block-foam insulation, a WeatherShield one-piece fiberglass roof, 82-inch sidewalls, Nordic Marble counters, a 10-cubic-foot 12V refrigerator and an 18,000-BTU Furrion Chill Cube with a standard second 13,500-BTU air conditioner. Two awnings (12 and 14 feet) and a free-standing dinette option extend the living space; a JBL sound system plays inside and out, and a 200-watt roof-solar package is optional.

The 308RL is published with 1,842 pounds of cargo capacity and a 1,185-pound tongue, so it needs a capable half-ton or a three-quarter-ton truck. Its 90-gallon gray tank is the largest in the line — useful for the longer stays this coach invites — against 45 gallons fresh and 30 black. For two who want a residential rear lounge, an island kitchen and real laundry capacity in the Hemisphere’s laminate build — with the identical Wildwood Heritage Glen to cross-shop — the 308RL is the couples flagship.

Forest River's Salem Hemisphere and its twin the Wildwood Heritage Glen are the same premium-laminate travel trailers built on the same factory line, differing mainly in graphics and décor and sharing an identical floorplan roster. Hemisphere sits at the top of the Salem / Wildwood travel-trailer ladder — a vacuum-laminated "Aluma Frame" coach with a one-piece fiberglass roof, Nordic Marble counters, an 18,000-BTU Furrion Chill Cube and an automotive windshield — in two tiers: a lighter Hyper-Lyte series of half-ton plans and a heavier full-Hemisphere series of triple-slide family and couples' coaches. The 308RL on this page is highlighted; each other profiled plan links to its own page. The line runs to roughly two dozen travel-trailer floorplans plus a fifth-wheel range; the highest-demand layouts are detailed here and the rest are catalogued on the line hub.

A full 45-gallon fresh tank is about 375 lb of water, 20% of the 308RL’s 1,842 lb cargo capacity, leaving 1,467 lb (367 lb per rated berth). Across 12 Salem Hemisphere & Heritage Glen floorplans the water share runs 13% to 29%, and 2 give up more than this one. Nearest on that share: Salem Hemisphere & Heritage Glen 24RBHL at 20% and Salem Hemisphere & Heritage Glen 301FAM at 21%.
