2026 Forest River Wildwood Heritage Glen / Salem Hemisphere Fifth WheelsROOST43

The Wildwood Heritage Glen Fifth Wheels ROOST43 leaves Forest River's factory at 15,044 lbs dry with 2,951 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 2,951 lbs before anything else goes in.

Pin weight is 2,830 lbs, 19% 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: 156 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 10th of 10 floorplans by dry weight, in a line that runs from 9,129 lbs to 15,044 lbs. It is the heaviest plan in the line, so the tow vehicle should be settled before the floorplan is.

Plan the tow on loaded weight, not the 15,044 lbs dry figure: half the published cargo capacity brings this plan to about 16,520 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: “The ROOST43 provides a new segment to the RV market with a combination of a destination trailer in fifth wheel form. This creates the opportunity to move from locations easier than bumper pulling and provides the most square footage in this segment of RVs (530 Sq.Ft. compared to 399 Sq.Ft.). The ROOST43 is feature packed with residential style kitchen appliances, HUGE rear den, two lofts, bath and a half, laundry…” 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 ROOST43 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.

• Dry weight, 15,044 lb: heaviest of ten; next is the 373MBRL (13,904 lb).
• Pin weight, 2,830 lb: heaviest of ten; next is the 376FAM (2,430 lb).
• Cargo capacity, 2,951 lb: second-largest of ten, between the 321DRL (2,841 lb) and the 380WDR (3,341 lb).
• Black tank, 78 gal: second-largest of ten, between the 356QB, 376FAM and 380WDR (60 gal) and the 36FL (91 gal).
• Pin weight as a share of dry weight, 18.8%: third-largest of ten, between the 369BL (18.4%) and the 286RL (19.9%).
• Length, 43 ft 9 in: longest of ten, level with the 36FL; next is the 373MBRL (43 ft 8 in).
• Grey tank, 78 gal: fifth-largest of ten, between the 280RE and 369BL (62 gal) and the 356QB (90 gal).
• Exterior height, 13 ft 5 in: shared with the 280RE, 286RL and 380WDR; 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 373MBRL (2027 page), the nearest lighter floorplan by dry weight, the ROOST43 is 1,140 lb heavier by dry weight, has 855 lb more cargo capacity, has a pin weight 490 lb heavier, is 1 in longer, stands 1 in lower, has a grey tank 18 gal larger and has a black tank 48 gal larger; 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, 16% of the ROOST43’s 2,951 lb cargo capacity, leaving 2,478 lb. Across 10 Wildwood Heritage Glen Fifth Wheels floorplans the water share runs 14% to 23%, and 8 give up more than this one. Nearest on that share: Wildwood Heritage Glen Fifth Wheels 380WDR at 14% and Wildwood Heritage Glen Fifth Wheels 321DRL at 17%.
