2026 Forest River Wildwood Heritage Glen / Salem Hemisphere Fifth Wheels380WDR

The Wildwood Heritage Glen Fifth Wheels 380WDR leaves Forest River's factory at 13,009 lbs dry with 3,341 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 3,341 lbs before anything else goes in.

Pin weight is 2,350 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: 172 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 7th 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 13,009 lbs dry figure: half the published cargo capacity brings this plan to about 14,679 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. 380WDR is a Wildwood Heritage Glen Fifth Wheels designation and this site does not decode it into a layout claim.

How the 380WDR 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.

• Cargo capacity, 3,341 lb: largest of ten; next is the ROOST43 (2,951 lb).
• Grey tank, 112 gal: largest of ten; next is the 376FAM (92 gal).
• Pin weight, 2,350 lb: third-heaviest of ten, between the 373MBRL (2,340 lb) and the 376FAM (2,430 lb).
• Dry weight, 13,009 lb: fourth-heaviest of ten, between the 36FL (12,954 lb) and the 376FAM (13,484 lb).
• Length, 42 ft 10 in: fifth-shortest of ten, between the 376FAM (42 ft 7 in) and the 356QB and 369BL (43 ft).
• Black tank, 60 gal: shared with the 356QB and 376FAM; of ten, five smaller and two larger, nearest the 286RL (32 gal) and the ROOST43 (78 gal).
• Pin weight as a share of dry weight, 18.1%: shared with the 321DRL; of ten, four smaller and four larger, nearest the 376FAM (18%) and the 369BL (18.4%).
• Exterior height, 13 ft 5 in: shared with the 280RE, 286RL and ROOST43; of ten, four lower and two taller, nearest the 36FL (13 ft 4 in) and the 373MBRL and 376FAM (13 ft 6 in).

Next to the 36FL, the nearest lighter floorplan by dry weight, the 380WDR is 55 lb heavier by dry weight, has 795 lb more cargo capacity, has a pin weight 325 lb heavier, is 11 in shorter, stands 1 in taller, has a grey tank 21 gal larger and has a black tank 31 gal smaller; the two publish the same fresh tank.

Next to the 376FAM, the nearest heavier floorplan by dry weight, the 380WDR is 475 lb lighter by dry weight, has 825 lb more cargo capacity, has a pin weight 80 lb lighter, is 3 in longer, stands 1 in lower and has a grey tank 20 gal larger; the two publish the same fresh tank and black 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, 14% of the 380WDR’s 3,341 lb cargo capacity, leaving 2,868 lb. Across 10 Wildwood Heritage Glen Fifth Wheels floorplans the water share runs 14% to 23%, and this plan’s is the lowest. Nearest on that share: Wildwood Heritage Glen Fifth Wheels ROOST43 at 16%.
