2026 Forest River Wildwood Heritage Glen / Salem Hemisphere Fifth Wheels369BL

The Wildwood Heritage Glen Fifth Wheels 369BL leaves Forest River's factory at 11,669 lbs dry with 2,481 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 57-gallon fresh tank spends 473 lbs of the 2,481 lbs before anything else goes in.

Pin weight is 2,150 lbs, 18% of the dry weight as published; it rises as the trailer is loaded and comes off the truck’s payload, not its towing rating, so check it against the payload on your own door sticker (pin weight and payload).

Off hookups: 92 gallons of grey and black capacity against 57 gallons of fresh water, so fresh water runs out first (tank sizes by length).

Against the rest of the Wildwood Heritage Glen Fifth Wheels roster this is the 5th of 10 floorplans by dry weight, in a line that runs from 9,129 lbs to 15,044 lbs. It sits in the middle of the line by weight.

Plan the tow on loaded weight, not the 11,669 lbs dry figure: half the published cargo capacity brings this plan to about 12,909 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: “Watch out the massive campsite-facing windows to keep track of the kids, or just enjoy the view in the 369BL. Sleep extra people or store extra gear in the tallest-in-class loft above the bunk room. A pantry unheard of in a bunk model, and bonus outside storage with fridge are just some of the features that put the 369BL ahead of the competition.” 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.

• Cargo capacity, 2,481 lb: second-smallest of ten, between the 373MBRL (2,096 lb) and the 280RE (2,500 lb).
• Pin weight as a share of dry weight, 18.4%: fourth-largest of ten, between the 321DRL and 380WDR (18.1%) and the ROOST43 (18.8%).
• Dry weight, 11,669 lb: fifth-lightest of ten, between the 356QB (11,249 lb) and the 36FL (12,954 lb).

Next to the 356QB, the nearest lighter floorplan by dry weight, the 369BL is 420 lb heavier by dry weight, has 60 lb less cargo capacity, has a pin weight 360 lb heavier, stands 1 in lower, has a grey tank 28 gal smaller and has a black tank 30 gal smaller; the two publish the same length and fresh tank.

Next to the 36FL, the nearest heavier floorplan by dry weight, the 369BL is 1,285 lb lighter by dry weight, has 65 lb less cargo capacity, has a pin weight 125 lb heavier, is 9 in shorter, stands 3 in lower, has a grey tank 29 gal smaller and has a black tank 61 gal smaller; the two publish the same fresh tank.

Heritage Glen's fifth-wheel roster is published as two tiers, the standard series and Elite Luxury, across eleven floorplans running 9,380 to 15,044 lb dry on pin weights of 1,790 to 2,830 lb. Forest River publishes no GVWR for any Heritage Glen fifth wheel, which means the one figure a buyer needs to compare against a truck's rating is absent from the factory's own spec channel.

A full 57-gallon fresh tank is about 473 lb of water, 19% of the 369BL’s 2,481 lb cargo capacity, leaving 2,008 lb. Across 10 Wildwood Heritage Glen Fifth Wheels floorplans the water share runs 14% to 23%, and 1 gives up more than this one. Nearest on that share: Wildwood Heritage Glen Fifth Wheels 280RE at 19% and Wildwood Heritage Glen Fifth Wheels 373MBRL at 23%.
