2026 Forest River Wildwood Heritage Glen / Salem Hemisphere Fifth Wheels376FAM

The Wildwood Heritage Glen Fifth Wheels 376FAM leaves Forest River's factory at 13,484 lbs dry with 2,516 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 2,516 lbs before anything else goes in.

Pin weight is 2,430 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: 152 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 8th of 10 floorplans by dry weight, in a line that runs from 9,129 lbs to 15,044 lbs. It sits in the heavier third of the line.

Plan the tow on loaded weight, not the 13,484 lbs dry figure: half the published cargo capacity brings this plan to about 14,742 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 publishes no floorplan description for this plan in the channel this page is built from - only the numeric specification block. Rather than describe a layout from the floorplan code, which would be a guess dressed as a fact, this page carries what the factory publishes and says where it stops. 376FAM is a Wildwood Heritage Glen Fifth Wheels designation and this site does not decode it into a layout claim.

How the 376FAM differs from the other nine Wildwood Heritage Glen Fifth Wheels. Most distinctive first. Sibling pages may cover other model years than this one (2026). How these ranks are worked out.

• Pin weight, 2,430 lb: second-heaviest of ten, between the 380WDR (2,350 lb) and the ROOST43 (2,830 lb).
• Grey tank, 92 gal: second-largest of ten, between the 36FL (91 gal) and the 380WDR (112 gal).
• Dry weight, 13,484 lb: third-heaviest of ten, between the 380WDR (13,009 lb) and the 373MBRL (13,904 lb).
• Cargo capacity, 2,516 lb: fourth-smallest of ten, between the 280RE (2,500 lb) and the 356QB (2,541 lb).
• Pin weight as a share of dry weight, 18%: fourth-smallest of ten, between the 373MBRL (16.8%) and the 321DRL and 380WDR (18.1%).
• Length, 42 ft 7 in: fourth-shortest of ten, between the 321DRL (36 ft 1 in) and the 380WDR (42 ft 10 in).
• Exterior height, 13 ft 6 in: tallest of ten, level with the 373MBRL; next are the 280RE, 286RL and two others (13 ft 5 in).
• Black tank, 60 gal: shared with the 356QB and 380WDR; of ten, five smaller and two larger, nearest the 286RL (32 gal) and the ROOST43 (78 gal).

Next to the 380WDR, the nearest lighter floorplan by dry weight, the 376FAM is 475 lb heavier by dry weight, has 825 lb less cargo capacity, has a pin weight 80 lb heavier, is 3 in shorter, stands 1 in taller and has a grey tank 20 gal smaller; the two publish the same fresh tank and black tank.

Next to the 373MBRL (2027 page), the nearest heavier floorplan by dry weight, the 376FAM is 420 lb lighter by dry weight, has 420 lb more cargo capacity, has a pin weight 90 lb heavier, is 1 ft 1 in shorter, has a grey tank 32 gal larger and has a black tank 30 gal larger; the two publish the same exterior height and 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 376FAM’s 2,516 lb cargo capacity, leaving 2,043 lb. Across 10 Wildwood Heritage Glen Fifth Wheels floorplans the water share runs 14% to 23%, and 3 give up more than this one. Nearest on that share: Wildwood Heritage Glen Fifth Wheels 356QB at 19% and Wildwood Heritage Glen Fifth Wheels 280RE at 19%.
