2026 Forest River Wildwood Heritage Glen / Salem Hemisphere21RBHL

The Wildwood Heritage Glen 21RBHL leaves Forest River's factory at 4,883 lbs dry with 2,712 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 45-gallon fresh tank spends 374 lbs of the 2,712 lbs before anything else goes in.

Tongue weight is 595 lbs, 12% of the dry weight as published; it rises as the trailer is loaded and counts against the tow vehicle’s tongue-weight and payload limits (tongue weight by size).

Off hookups: 90 gallons of grey and black capacity against 45 gallons of fresh water, so fresh water runs out first (tank sizes by length).

Against the rest of the Wildwood Heritage Glen roster this is the 1st of 15 floorplans by dry weight, in a line that runs from 4,883 lbs to 9,893 lbs. It is the lightest plan in the line, which makes it the one to look at first if the tow vehicle is the constraint.

Plan the tow on loaded weight, not the 4,883 lbs dry figure: half the published cargo capacity brings this plan to about 6,239 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. 21RBHL is a Wildwood Heritage Glen designation and this site does not decode it into a layout claim.

How the 21RBHL differs from the other fourteen Wildwood Heritage Glen floorplans. Most distinctive first. Sibling pages may cover other model years than this one (2026). How these ranks are worked out.

• Dry weight, 4,883 lb: lightest of fifteen; next is the 24RBHL (5,808 lb).
• Tongue weight, 595 lb: lightest of fifteen; next is the 245BHHL (600 lb).
• Length, 24 ft 11 in: shortest of fifteen; next is the 24RBHL (29 ft 7 in).
• Exterior height, 11 ft 1 in: lowest of fifteen; next are the 245BHHL, 24RBHL and 255RBHL (11 ft 3 in).
• Cargo capacity, 2,712 lb: second-largest of fifteen, between the 28RKHL (2,672 lb) and the 25BHHL (2,927 lb).
• Tongue weight as a share of dry weight, 12.2%: seventh-smallest of fifteen, between the 265BSRB and 28RKHL (12.1%) and the 308RL (12.4%).
• Grey tank, 60 gal: smallest of fifteen, level with the 24RBHL, 25BHHL and four others; next is the 310BHI (66 gal).

Next to the 24RBHL, the nearest heavier floorplan by dry weight, the 21RBHL is 925 lb lighter by dry weight, has 830 lb more cargo capacity, has a tongue weight 95 lb lighter, is 4 ft 8 in shorter and stands 2 in lower; the two publish the same fresh tank, grey tank and black tank.

Wildwood Heritage Glen is published as two travel-trailer groupings - the standard roster and a Hyper-Lyte tier - and the two overlap enough on weight that the badge is a poor guide on its own. Dry weight runs 4,883 to 9,893 lb and cargo capacity 1,282 to 2,927 lb, so the tow vehicle needs checking rather than assuming. Nine of the twenty-two published plans are dealer-stock-only. Forest River publishes no GVWR for any Heritage Glen travel trailer.

A full 45-gallon fresh tank is about 374 lb of water, 14% of the 21RBHL’s 2,712 lb cargo capacity, leaving 2,338 lb. Across 15 Wildwood Heritage Glen floorplans the water share runs 13% to 29%, and 13 give up more than this one. Nearest on that share: Wildwood Heritage Glen 25BHHL at 13% and Wildwood Heritage Glen 28RKHL at 14%.
