2026 Forest River Cherokee Timberwolf39JM

The Cherokee Timberwolf 39JM has 876 lbs of cargo capacity between 12,589 lbs dry and its 13,465 lbs GVWR, 7% of that rating; filling its 40-gallon fresh tank at 8.3 lb a gallon uses 332 lbs of it (how to read trailer weights).

Tongue weight is 1,465 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: 160 gallons of grey and black capacity against 40 gallons of fresh water, so fresh water runs out first (tank sizes by length).

Against the rest of the Cherokee Timberwolf roster this is the 11th of 11 floorplans by dry weight, in a line that runs from 7,109 lbs to 12,589 lbs. It is the heaviest plan in the line, so the tow vehicle should be settled before the floorplan is.

Plan the tow on loaded weight, not the 12,589 lbs dry figure: half the published cargo capacity brings this plan to about 13,027 lbs, and the published GVWR of 13,465 lbs is the limit (how to read trailer weights).

Forest River’s line listing and this floorplan’s own factory page agree on all 4 shared figures. Dry weight plus cargo capacity equals the published GVWR exactly. 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. 39JM is a Cherokee Timberwolf designation and this site does not decode it into a layout claim.

How the 39JM differs from the other ten Cherokee Timberwolf floorplans. Most distinctive first. How these ranks are worked out.

• Dry weight, 12,589 lb: heaviest of eleven; next is the 39AL (11,994 lb).
• Cargo capacity, 876 lb: smallest of eleven; next is the 39AL (1,186 lb).
• Cargo capacity as a share of GVWR, 6.5%: smallest of eleven; next is the 39AL (9%).
• Black tank, 80 gal: largest of eleven; next are the 39DC, 39HBA and 39NA (70 gal).
• GVWR, 13,465 lb: third-highest of eleven, between the 39HBA (13,330 lb) and the 39DC (13,470 lb).
• Tongue weight, 1,465 lb: third-heaviest of eleven, between the 39HBA (1,330 lb) and the 39DC (1,470 lb).
• Tongue weight as a share of dry weight, 11.6%: fourth-smallest of eleven, between the 39DK (10.5%) and the 27MDK and 39HBA (12.3%).
• Length, 43 ft 4 in: fifth-longest of eleven, between the 39DL and 39NA (42 ft 8 in) and the 39DK (43 ft 9 in).
• Exterior height, 13 ft 4 in: shared with the 39DL; of eleven, two lower and seven taller, nearest the 39NA (12 ft 11 in) and the 16ML, 20OG and five others (13 ft 6 in).
• Grey tank, 80 gal: largest of eleven, level with the 39DC, 39HBA and 39NA; next are the 39AL and 39DK (70 gal).

Next to the 39AL, the nearest lighter floorplan by dry weight, the 39JM is 595 lb heavier by dry weight, has a GVWR 285 lb higher, has 310 lb less cargo capacity, has a tongue weight 285 lb heavier, is 1 ft 8 in shorter, stands 2 in lower, has a grey tank 10 gal larger and has a black tank 40 gal larger; the two publish the same fresh tank.

Timberwolf carries the widest cargo spread of any line in this group: 876 lb at the bottom of the roster and 4,296 lb at the top, a factor of nearly five, on trailers 7,109 to 12,589 lb dry. Two of the eleven published plans are in a separate mini-loft travel-trailer grouping and the other nine are destination trailers. Hitch weight stays between 1,040 and 1,614 lb across the whole range, so the hitch figure alone will not tell you which end of the line you are looking at - the cargo number will.

A full 40-gallon fresh tank is about 332 lb of water (water counts as cargo: 49 CFR 571.120 S10.4.2), 38% of the 39JM’s 876 lb cargo capacity, leaving 544 lb. Across 11 Cherokee Timberwolf floorplans the water share runs 8% to 38%, and this plan’s is the highest. Nearest on that share: Cherokee Timberwolf 39AL at 28%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.120 S10.4.3).
