2026 Forest River Wildwood Heritage Glen / Salem Hemisphere310BHI

The Wildwood Heritage Glen 310BHI leaves Forest River's factory at 9,333 lbs dry with 2,112 lbs of cargo capacity. Forest River publishes no GVWR for this line, so the loaded rating is not quoted on this page and is not computed from the other two figures. What the cargo number covers is defined by the factory: fresh water, gear, food, batteries and every dealer-installed accessory come out of it. Fresh water is 8.3 lb per gallon, so filling the 45-gallon fresh tank spends 374 lbs of the 2,112 lbs before anything else goes in.

Tongue weight is 1,245 lbs, 13% of the dry weight as published; it rises as the trailer is loaded and counts against the tow vehicle’s tongue-weight and payload limits (tongue weight by size).

Off hookups: 96 gallons of grey and black capacity against 45 gallons of fresh water, so fresh water runs out first (tank sizes by length).

Against the rest of the Wildwood Heritage Glen roster this is the 12th of 15 floorplans by dry weight, in a line that runs from 4,883 lbs to 9,893 lbs. It sits in the heavier third of the line.

Plan the tow on loaded weight, not the 9,333 lbs dry figure: half the published cargo capacity brings this plan to about 10,389 lbs. Forest River publishes no loaded rating for this line, so the ceiling is the one on the trailer’s own weight label (how to read trailer weights).

Forest River’s line listing and this floorplan’s own factory page agree on all 4 shared figures. No GVWR is published for this line, so dry plus cargo has no rating to check against. A missing row means Forest River does not publish that figure (how figures are verified).

Forest River's own description of this floorplan reads: “Camping with your family shouldn't require you to sacrifice your living space. With the 310BHI, you don't have to. This floorplan offers a MASSIVE outside kitchen, direct viewing of your campsite, a standard 50" TV, and a pantry most houses would dream of. If that wasn't enough, the 310BHI comes standard with stackable washer/dryer prep thoughtfully located in the bedroom closet/wardrobe.” That is the factory's marketing copy rather than a specification, and nothing in it is treated as a verified field on this page - layout descriptions, sleeping arrangements and feature claims in factory copy are not carried into the spec table unless the factory also publishes them as specifications.

How the 310BHI differs from the other fourteen Wildwood Heritage Glen floorplans. Most distinctive first. Sibling pages may cover other model years than this one (2026). How these ranks are worked out.

• Tongue weight, 1,245 lb: third-heaviest of fifteen, between the 305RLOK (1,240 lb) and the 314BUD (1,310 lb).
• Dry weight, 9,333 lb: fourth-heaviest of fifteen, between the 323RLI (9,278 lb) and the 308RL (9,543 lb).
• Tongue weight as a share of dry weight, 13.3%: fourth-largest of fifteen, between the 255RBHL (13.1%) and the 261FKRB (13.5%).
• Length, 38 ft 1 in: fourth-longest of fifteen, between the 308RL (38 ft) and the 314BUD and 323RLI (38 ft 9 in).
• Cargo capacity, 2,112 lb: seventh-largest of fifteen, between the 265BSRB (1,942 lb) and the 323RLI (2,127 lb).
• Exterior height, 11 ft 8 in: tallest of fifteen, level with the 305RLOK, 308RL and 323RLI; next is the 301FAM (11 ft 7 in).
• Grey tank, 66 gal: eighth-smallest of fifteen, between the 21RBHL, 24RBHL and five others (60 gal) and the 265BSRB, 305RLOK and 314BUD (78 gal).

Next to the 323RLI, the nearest lighter floorplan by dry weight, the 310BHI is 55 lb heavier by dry weight, has 15 lb less cargo capacity, has a tongue weight 40 lb heavier, is 8 in shorter and has a grey tank 6 gal larger; the two publish the same exterior height, fresh tank and black tank.

Next to the 308RL, the nearest heavier floorplan by dry weight, the 310BHI is 210 lb lighter by dry weight, has 270 lb more cargo capacity, has a tongue weight 60 lb heavier, is 1 in longer and has a grey tank 24 gal smaller; the two publish the same exterior height, fresh tank and black tank.

Wildwood Heritage Glen is published as two travel-trailer groupings - the standard roster and a Hyper-Lyte tier - and the two overlap enough on weight that the badge is a poor guide on its own. Dry weight runs 4,883 to 9,893 lb and cargo capacity 1,282 to 2,927 lb, so the tow vehicle needs checking rather than assuming. Nine of the twenty-two published plans are dealer-stock-only. Forest River publishes no GVWR for any Heritage Glen travel trailer.

A full 45-gallon fresh tank is about 374 lb of water, 18% of the 310BHI’s 2,112 lb cargo capacity, leaving 1,738 lb. Across 15 Wildwood Heritage Glen floorplans the water share runs 13% to 29%, and 8 give up more than this one. Nearest on that share: Wildwood Heritage Glen 323RLI at 18% and Wildwood Heritage Glen 265BSRB at 19%.
