2026 Forest River Wildwood Heritage Glen 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.

Dry pin weight is 2,150 lbs, which is 18% of the dry weight. That figure lands on the truck's rear axle and comes straight off its payload rating - not its towing rating, which is the number most often quoted and the wrong one for this decision. Pin weight rises as the trailer is loaded, and a fifth wheel loaded toward its cargo capacity will put substantially more than 2,150 lbs over the bed. Read the payload figure on your own door sticker rather than a brochure maximum for the model.

Tank capacities are 57 gallons fresh, 62 grey and 30 black, 92 gallons of waste capacity against 57 gallons of supply. The ratio is what governs how long the trailer can sit off hookups: waste capacity exceeds fresh, so the fresh tank is the binding constraint and refilling extends the stay. Forest River publishes these three figures per floorplan, and they are the factory's numbers rather than a segment average.

Against the rest of the Wildwood Heritage Glen Fifth Wheels roster this is the 6th of 11 floorplans by dry weight, in a line that runs from 9,380 lbs to 15,044 lbs. It sits in the middle of the line by weight. Comparing floorplans inside one line is more reliable than comparing across brands, because every figure here comes from the same factory channel on the same day.

A useful way to read these figures is to stop planning against the dry weight. Nobody tows a trailer at 11,669 lbs: that is the weight before water, batteries, propane, bedding, food, tools and anything the dealer bolted on. Load half the published cargo capacity and this plan is already near 12,909 lbs on the road. Because Forest River publishes no loaded rating for this line, the ceiling has to come from the trailer's own weight label rather than from this page, and the comparison you make against the tow vehicle should use the loaded figure.

Every number above was captured twice from Forest River and checked against itself before it was published. The line roster block and the individual floorplan page are two separate factory renderings of the same trailer, and this plan's 4 shared figures agree exactly on both. There is no published GVWR on this line, so the usual arithmetic check - dry plus cargo equals the rating - has nothing to test against here. Where a figure is missing from this page it is because Forest River does not publish it in this channel, not because it was hard to find - and the row says so rather than being quietly dropped.

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.

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 dry pin weights of 1,790 to 2,830 lb. The lightest plan is a genuine three-quarter-ton trailer and the heaviest is not, so the tier badge is less useful here than the pin number. 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.

This floorplan carries its water comfortably. A full 57-gallon fresh tank is roughly 19% of the 2,481-pound cargo capacity, leaving the 369BL with a usable gear budget even when you tow full.

The published dry pin weight of 2,150 pounds is 18% of this floorplan’s 11,669-pound dry weight. Fifth-wheel pin weight rides in the bed of the truck, so it comes off payload rather than off tow rating — and it rises with the trailer as you load it, not in proportion to what you put over the axles.

Tank balance is generous here: 57 gallons of fresh against 62 grey and 30 black, so waste capacity keeps pace with supply and the fresh tank is the constraint that ends a dry stay.

Ranked by dry weight, the 369BL sits 4 of 8 in the Wildwood Heritage Glen Fifth Wheels line: 11,669 pounds against a line that runs from 9,380 to 15,044 pounds. That position is the useful thing to know, because the plans immediately either side of it are the real alternatives.

Either side of it in the same line: Wildwood Heritage Glen Fifth Wheels 356QB is 420 pounds lighter at 11,249 lb dry; and Wildwood Heritage Glen Fifth Wheels 36FL is 1,285 pounds heavier at 12,954 lb dry.

Against the 369BL: the Cardinal 38DEN is 31 lb lighter and 1 ft longer; the Reflection 311BHS is 31 lb heavier and 6 ft shorter; the Cougar 364BHL is 44 lb lighter and 4 ft shorter. Those are differences in the published numbers only — what they cost, how they are built and how they live are separate questions each of those pages answers on its own terms.

Those are the nearest fifth wheels from other lines by weight — one per line, picked by proximity on that figure and nothing else. They are listed so the same tow vehicle can be checked against real alternatives, not because they are equivalent inside; layout, build and price diverge sharply across that group.

For scale, the Wildwood Heritage Glen Fifth Wheels floorplans profiled here run 9,380 to 15,044 pounds dry and 34 to 44 feet of exterior length across 8 plans. Where a floorplan falls in that spread usually says more about which vehicle can tow it, and which site it fits, than the layout name does.

This catalog tracks 18 specification fields per floorplan. Named sources publish 10 of them for the 369BL. The rest are not shown, because the alternative is reading a figure across from a sibling floorplan or from what the segment usually does — and a number nobody published is worth less than an admitted gap.

Not published for this floorplan: GVWR, interior height, sleeps, slide count, axle count, tire specification, refrigerator, air conditioning. If you find one of these in a manufacturer document for this plan, it belongs on this page.

The completeness figure at the foot of this page (83%) measures the same thing on the full field set: it is a measurement of how much this floorplan’s manufacturer publishes, not of how much research went into the page.

How every figure here was sourced and checked is set out on the methodology page.
