2026 Forest River Wildwood Heritage Glen / Salem Hemisphere301FAM

The Wildwood Heritage Glen 301FAM leaves Forest River's factory at 9,893 lbs dry with 1,772 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 1,772 lbs before anything else goes in.

Tongue weight is 1,465 lbs, 15% 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 14th 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 9,893 lbs dry figure: half the published cargo capacity brings this plan to about 10,779 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. 301FAM is a Wildwood Heritage Glen designation and this site does not decode it into a layout claim.

How the 301FAM 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.

• Tongue weight, 1,465 lb: heaviest of fifteen; next is the 314BUD (1,310 lb).
• Length, 38 ft 10 in: longest of fifteen; next are the 314BUD and 323RLI (38 ft 9 in).
• Dry weight, 9,893 lb: heaviest of fifteen, level with the 305RLOK; next is the 308RL (9,543 lb).
• Cargo capacity, 1,772 lb: fifth-smallest of fifteen, between the 245BHHL (1,687 lb) and the 308RL (1,842 lb).
• Tongue weight as a share of dry weight, 14.8%: largest of fifteen, level with the 314BUD; next is the 261FKRB (13.5%).
• Exterior height, 11 ft 7 in: fifth-tallest of fifteen, between the 261FKRB, 265BSRB and 314BUD (11 ft 6 in) and the 305RLOK, 308RL and two others (11 ft 8 in).
• Grey tank, 90 gal: largest of fifteen, level with the 245BHHL, 255RBHL and 308RL; next are the 265BSRB, 305RLOK and 314BUD (78 gal).

Next to the 308RL, the nearest lighter floorplan by dry weight, the 301FAM is 350 lb heavier by dry weight, has 70 lb less cargo capacity, has a tongue weight 280 lb heavier, is 10 in longer and stands 1 in lower; the two publish the same fresh tank, grey tank and black tank.

Next to the 305RLOK (2027 page), the floorplan with the same dry weight, the 301FAM has 225 lb more cargo capacity, has a tongue weight 225 lb heavier, is 1 ft 1 in longer, stands 1 in lower and has a grey tank 12 gal larger; the two publish the same dry weight, fresh 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, 21% of the 301FAM’s 1,772 lb cargo capacity, leaving 1,398 lb. Across 15 Wildwood Heritage Glen floorplans the water share runs 13% to 29%, and 4 give up more than this one. Nearest on that share: Wildwood Heritage Glen 308RL at 20% and Wildwood Heritage Glen 245BHHL at 22%.
