2026 Forest River Cascade39DLC

The Cascade 39DLC has 2,015 lbs of cargo capacity between 11,327 lbs dry and its 13,342 lbs GVWR, 15% 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 1,342 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: 80 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 Cascade roster this is the 16th of 16 floorplans by dry weight, in a line that runs from 2,604 lbs to 11,327 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 11,327 lbs dry figure: half the published cargo capacity brings this plan to about 12,335 lbs, and the published GVWR of 13,342 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. 39DLC is a Cascade designation and this site does not decode it into a layout claim.

How the 39DLC differs from the other fifteen Cascade floorplans. Most distinctive first. How these ranks are worked out.

• Dry weight, 11,327 lb: heaviest of sixteen; next is the 39TNC (8,885 lb).
• GVWR, 13,342 lb: highest of sixteen; next is the 39TNC (13,140 lb).
• Tongue weight, 1,342 lb: heaviest of sixteen; next is the 39TNC (1,140 lb).
• Length, 42 ft 8 in: longest of sixteen; next is the 39TNC (40 ft 7 in).
• Cargo capacity as a share of GVWR, 15.1%: third-smallest of sixteen, between the 17MPHC (14.3%) and the 26KFC (17.2%).
• Cargo capacity, 2,015 lb: fifth-largest of sixteen, between the 301BHC (1,932 lb) and the 20OGC (2,861 lb).
• Tongue weight as a share of dry weight, 11.8%: fifth-smallest of sixteen, between the 17THHC and 26SSC (11.7%) and the 301BHC (11.9%).
• Exterior height, 13 ft 6 in: tallest of sixteen, level with the 20OGC; next is the 39TNC (12 ft 9 in).
• Grey tank, 40 gal: largest of sixteen, level with the 20OGC and 39TNC; next are the 23MSC, 26KFC and five others (38 gal).
• Black tank, 40 gal: largest of sixteen, level with the 20OGC and 39TNC; next are the 23MSC, 26KFC and four others (38 gal).
• Fresh tank, 40 gal: shared with the 20OGC and 39TNC; of sixteen, six smaller and seven larger, nearest the 14BHLPC, 17LPC and two others (26 gal) and the 23MSC, 26KFC and five others (52 gal).

Next to the 39TNC, the nearest lighter floorplan by dry weight, the 39DLC is 2,442 lb heavier by dry weight, has a GVWR 202 lb higher, has 2,240 lb less cargo capacity, has a tongue weight 202 lb heavier, is 2 ft 1 in longer and stands 9 in taller; the two publish the same fresh tank, grey tank and black tank.

Cascade covers a wider span than any other Forest River travel-trailer line this site has catalogued: thirty-three published floorplans in five factory groupings - single axle, tandem axle, tandem-axle toy hauler, fish house and destination - running from 2,604 lb dry at 17 feet 3 inches to 11,327 lb at 42 feet 8 inches. Tongue weight runs 320 to 1,342 lb over that span. The grouping a plan belongs to predicts its class far better than its floorplan number does, so both are in the table below.

A full 40-gallon fresh tank is about 332 lb of water (water counts as cargo: 49 CFR 571.120 S10.4.2), 16% of the 39DLC’s 2,015 lb cargo capacity, leaving 1,683 lb. Across 16 Cascade floorplans the water share runs 8% to 32%, and 10 give up more than this one. Nearest on that share: Cascade 26LPC at 14% and Cascade 17SCC at 17%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.120 S10.4.3).
