2026 Salem Hemisphere 310BHI

The Salem Hemisphere 310BHI is the full-Hemisphere family bunkhouse — a rear bunk room with a convertible sofa/bed, a front bedroom, a kitchen island and direct sightlines across the campsite, all opened up by three slide-outs in a 38-foot-1 body. A standard 50-inch TV, a pantry the factory cheerfully calls house-sized, and stackable washer/dryer prep in the bedroom wardrobe round it out. Its twin in the Wildwood Heritage Glen 310BHI 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. Outside, a massive exterior kitchen and a pair of awnings (10 and 12 feet) extend the living space; a JBL sound system plays inside and out, and a 200-watt roof-solar package is optional.

With an 11,445-pound derived GVWR the 310BHI leaves about 2,112 pounds of cargo capacity and a 1,245-pound tongue, so it needs a capable half-ton or a three-quarter-ton truck and weight distribution. Fresh, gray and black tanks run 45, 66 and 30 gallons. For a family that wants a real bunk room, an island kitchen, a huge outside kitchen and laundry prep in the Hemisphere’s laminate build — with the identical Wildwood Heritage Glen to cross-shop — the 310BHI is the line’s family workhorse.

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 310BHI 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.

This floorplan carries its water comfortably. A full 45-gallon fresh tank is roughly 18% of the 2,112-pound cargo capacity, leaving the 310BHI with a usable gear budget even when you tow full.

The published dry tongue weight of 1,245 pounds is 13% of the 9,333-pound dry weight, which sits inside the 10–15% band usually quoted for stable towing. It is still a dry figure: loading the front pass-through and the fresh tank both push it up.

Nothing above changes the ceiling. Loaded to its 11,445-pound GVWR the 310BHI is towing 2,112 pounds more than its 9,333-pound dry figure, and that is the number your vehicle has to be rated for — not the brochure weight.

Tank balance is generous here: 45 gallons of fresh against 66 grey and 30 black, so waste capacity keeps pace with supply and the fresh tank is the constraint that ends a dry stay.

Ranked by GVWR, the 310BHI sits 10 of 12 in the Salem Hemisphere & Heritage Glen line: 11,445 pounds against a line that runs from 7,595 to 11,665 pounds. That position is the useful thing to know, because the plans immediately either side of it are the real alternatives.

Either side of it in the same line: Salem Hemisphere & Heritage Glen 323RLI is 40 pounds lighter at 11,405 lb GVWR; and Salem Hemisphere & Heritage Glen 314BUD is 65 pounds heavier at 11,510 lb GVWR.

Against the 310BHI: the Zinger 340BH is 5 lb heavier and sleeps 5 more; the Coachmen Catalina 333DORM is 13 lb heavier and sleeps 1 fewer; the Nightfall 24N is 45 lb lighter and 8 ft shorter. Those are differences in the published numbers only — what they cost, how they are built and how they live are separate questions each of those pages answers on its own terms.

Those are the nearest travel trailers from other lines by weight — one per line, picked by proximity on that figure and nothing else. They are listed so the same tow vehicle can be checked against real alternatives, not because they are equivalent inside; layout, build and price diverge sharply across that group.

For scale, the Salem Hemisphere & Heritage Glen floorplans profiled here run 4,883 to 9,893 pounds dry and 25 to 39 feet of exterior length across 12 plans. Where a floorplan falls in that spread usually says more about which vehicle can tow it, and which site it fits, than the layout name does.

Every profiled floorplan in this line, with the full weight table, is on the Salem Hemisphere & Heritage Glen line hub.

This catalog tracks 18 specification fields per floorplan. Named sources publish 16 of them for the 310BHI. The rest are not shown, because the alternative is reading a figure across from a sibling floorplan or from what the segment usually does — and a number nobody published is worth less than an admitted gap.

Not published for this floorplan: interior height, awning, tire size (a tire description is published, a size is not). If you find one of these in a manufacturer document for this plan, it belongs on this page.

The completeness figure at the foot of this page (95%) measures the same thing on the full field set: it is a measurement of how much this floorplan’s manufacturer publishes, not of how much research went into the page.

Values on this page carrying an asterisk were derived by arithmetic from published figures, or come from a single source, rather than being printed directly by the manufacturer. The flag travels with the number into the downloadable spec sheet.

How every figure here was sourced and checked is set out on the methodology page.
