2026 Forest River Wildwood Heritage Glen / Salem Hemisphere308RL

The Wildwood Heritage Glen 308RL leaves Forest River's factory at 9,543 lbs dry with 1,842 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 1,842 lbs before anything else goes in.

Tongue weight is 1,185 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: 120 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 13th of 15 floorplans by dry weight, in a line that runs from 4,883 lbs to 9,893 lbs. It sits in the heavier third of the line.

Plan the tow on loaded weight, not the 9,543 lbs dry figure: half the published cargo capacity brings this plan to about 10,464 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: “Touting 3 slide-outs, the 308RL is the most spacious Hemisphere Travel Trailer for coupes. Enjoy a breath-taking view of your campsite in the living room or relax in the wide-open bedroom. Past the bedroom you'll find a WALK-IN wardrobe, and washer/dryer prep area spacious enough for separate washer & dryer. (This is the only model without a windshield, because we didn't think your laundry would care to see outside).” 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 308RL 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, 9,543 lb: third-heaviest of fifteen, between the 310BHI (9,333 lb) and the 301FAM and 305RLOK (9,893 lb).
• Length, 38 ft: fifth-longest of fifteen, between the 305RLOK (37 ft 9 in) and the 310BHI (38 ft 1 in).
• Cargo capacity, 1,842 lb: sixth-smallest of fifteen, between the 301FAM (1,772 lb) and the 24RBHL (1,882 lb).
• Tongue weight, 1,185 lb: sixth-heaviest of fifteen, between the 261FKRB (1,020 lb) and the 323RLI (1,205 lb).
• Exterior height, 11 ft 8 in: tallest of fifteen, level with the 305RLOK, 310BHI and 323RLI; next is the 301FAM (11 ft 7 in).
• Grey tank, 90 gal: largest of fifteen, level with the 245BHHL, 255RBHL and 301FAM; next are the 265BSRB, 305RLOK and 314BUD (78 gal).
• Tongue weight as a share of dry weight, 12.4%: eighth-smallest of fifteen, between the 21RBHL (12.2%) and the 305RLOK (12.5%).

Next to the 310BHI, the nearest lighter floorplan by dry weight, the 308RL is 210 lb heavier by dry weight, has 270 lb less cargo capacity, has a tongue weight 60 lb lighter, is 1 in shorter and has a grey tank 24 gal larger; the two publish the same exterior height, fresh tank and black tank.

Next to the 301FAM, the nearest heavier floorplan by dry weight, the 308RL is 350 lb lighter by dry weight, has 70 lb more cargo capacity, has a tongue weight 280 lb lighter, is 10 in shorter and stands 1 in taller; 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, 20% of the 308RL’s 1,842 lb cargo capacity, leaving 1,468 lb. Across 15 Wildwood Heritage Glen floorplans the water share runs 13% to 29%, and 5 give up more than this one. Nearest on that share: Wildwood Heritage Glen 24RBHL at 20% and Wildwood Heritage Glen 301FAM at 21%.
