01 What makes it unique
The Wildwood Heritage Glen Fifth Wheels 321DRL leaves Forest River's factory at 11,184 lbs dry with 2,841 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 2,841 lbs before anything else goes in.
Pin weight is 2,025 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: 90 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 3rd of 10 floorplans by dry weight, in a line that runs from 9,129 lbs to 15,044 lbs. It sits in the lighter third of the line.
Plan the tow on loaded weight, not the 11,184 lbs dry figure: half the published cargo capacity brings this plan to about 12,604 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. 321DRL is a Wildwood Heritage Glen Fifth Wheels designation and this site does not decode it into a layout claim.
How the 321DRL 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, 11,184 lb: third-lightest of ten, between the 286RL (9,380 lb) and the 356QB (11,249 lb).
- Cargo capacity, 2,841 lb: third-largest of ten, between the 286RL (2,691 lb) and the ROOST43 (2,951 lb).
- Length, 36 ft 1 in: third-shortest of ten, between the 286RL (33 ft 11 in) and the 376FAM (42 ft 7 in).
- Exterior height, 13 ft 3 in: third-lowest of ten, between the 356QB (13 ft 2 in) and the 36FL (13 ft 4 in).
- Grey tank, 60 gal: smallest of ten, level with the 286RL and 373MBRL; next are the 280RE and 369BL (62 gal).
- Black tank, 30 gal: smallest of ten, level with the 280RE, 369BL and 373MBRL; next is the 286RL (32 gal).
- Pin weight, 2,025 lb: shared with the 36FL; of ten, three lighter and five heavier, nearest the 286RL (1,871 lb) and the 369BL (2,150 lb).
- Pin weight as a share of dry weight, 18.1%: shared with the 380WDR; of ten, four smaller and four larger, nearest the 376FAM (18%) and the 369BL (18.4%).
Next to the 286RL, the nearest lighter floorplan by dry weight, the 321DRL is 1,804 lb heavier by dry weight, has 150 lb more cargo capacity, has a pin weight 154 lb heavier, is 2 ft 2 in longer, stands 2 in lower and has a black tank 2 gal smaller; the two publish the same fresh tank and grey tank.
Next to the 356QB, the nearest heavier floorplan by dry weight, the 321DRL is 65 lb lighter by dry weight, has 300 lb more cargo capacity, has a pin weight 235 lb heavier, is 6 ft 11 in shorter, stands 1 in taller, has a grey tank 30 gal smaller and has a black tank 30 gal smaller; the two publish the same fresh tank.

The 2027 model year, as Forest River lists it
Forest River’s own floorplan page lists the 2027 Wildwood Heritage Glen Fifth Wheels 321DRL with the figures below (read 22 Oct 2026). They are that year’s record. The specifications above are the 2026 record; the two are not merged, and neither fills a gap in the other. Every weight, dimension and tank figure in it matches the 2026 record above. Forest River publishes no GVWR for this floorplan, so none is shown and none is computed.

Forest River also lists the 321DRL under a second badge, Salem Hemisphere, with the same floorplan code, and every Forest River roster saved for this site that lists it under both badges prints the same pin weight, dry weight, cargo capacity and length for it. This page carries both names; there is no second page set. How the two badges compare.
03 The Wildwood Heritage Glen Fifth Wheels floorplan family
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.
| Floorplan | Nominal | Dry weight (lb) | Cargo, CCC (lb) | Notable |
|---|---|---|---|---|
| 286RL | 33' 11" | 9,380 | 2,691 | Heritage Glen Fifth Wheels |
| 325RL - DSO | 37' 8" | 10,594 | 3,491 | Dealer stock only |

| ROOST43 | 43' 9" | 15,044 | 2,951 | Heritage Glen Fifth Wheels |
Heritage Glen's fifth-wheel side is published in two tiers, the standard series and Elite Luxury, across eleven floorplans - three of them dealer-stock-only. Forest River publishes dry weight, cargo capacity, pin weight, all three exterior dimensions and all three tank capacities for every plan, awning size for nine, and no GVWR for any of them. That row reads as unpublished rather than carrying a figure derived from cargo capacity. Sleeping capacity, axle count, tire size and MSRP are not published either. The travel-trailer side of Heritage Glen is a separate factory roster with its own page.
04 Notes on this floorplan
What Forest River does not publish for this line
Sleeping capacity, axle count, tire size and MSRP are absent from Forest River's specification channel for Wildwood Heritage Glen Fifth Wheels, so they are absent here. They are not estimated from the segment, not carried over from a sibling floorplan, and not taken from a dealer listing quoting itself. A tire size in particular is a safety-relevant number that differs between two codes a digit apart, and this site does not guess one.
There is no factory GVWR for this trailer
Forest River publishes dry weight, cargo capacity and pin weight for every Wildwood Heritage Glen Fifth Wheels floorplan and publishes no GVWR for any of them. The factory's own glossary defines cargo capacity as GVWR minus UVW, which means the rating can be worked out - and a figure you worked out is not a figure the manufacturer published, so this page does not print one. Use the weight label on the trailer itself, which every Forest River unit carries.
Awning size is not published for this floorplan
Forest River publishes an awning size for some Wildwood Heritage Glen Fifth Wheels floorplans and not for this one. The row reads as unpublished rather than being filled from a neighbouring plan in the same roster.
Weigh it before you tow it
Forest River calls its unloaded weight an estimated average for a standard build, and options and dealer add-ons change it, so weigh your own trailer loaded the way you travel (how figures are verified).
05 How it compares
9,380 lbs dry against this plan's 11,184 lbs, a difference of 1,804 lbs.
11,249 lbs dry, 65 lbs more than this plan, and 2,541 lbs of cargo capacity against this one's 2,841 lbs.
3,341 lbs of cargo capacity, the highest of the 10 Wildwood Heritage Glen Fifth Wheels floorplans profiled here. If payload rather than length is the binding constraint, that is the plan to compare against.
06 Loading it for a trip
A full 57-gallon fresh tank is about 473 lb of water, 17% of the 321DRL’s 2,841 lb cargo capacity, leaving 2,368 lb. Across 10 Wildwood Heritage Glen Fifth Wheels floorplans the water share runs 14% to 23%, and 7 give up more than this one. Nearest on that share: Wildwood Heritage Glen Fifth Wheels ROOST43 at 16% and Wildwood Heritage Glen Fifth Wheels 286RL at 18%.
07 Where this floorplan sits
Closest sibling: the Wildwood Heritage Glen Fifth Wheels 286RL, nearest on the published figures. It differs on 5 of the 7 fields both publish (this plan first): length 36 ft 1 in vs 33 ft 11 in; dry weight 11,184 lb vs 9,380 lb; cargo capacity 2,841 lb vs 2,691 lb; hitch weight 2,025 lb vs 1,871 lb; black tank 30 gal vs 32 gal. They match on fresh tank and grey tank.
