2026 Forest River Cascade17THHC

The Cascade 17THHC has 535 lbs of cargo capacity between 5,167 lbs dry and its 5,702 lbs GVWR, 9% of that rating; filling its 13-gallon fresh tank at 8.3 lb a gallon uses 108 lbs of it (how to read trailer weights).

Tongue weight is 602 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: 57 gallons of grey and black capacity against 13 gallons of fresh water, so fresh water runs out first (tank sizes by length).

Against the rest of the Cascade roster this is the 7th of 16 floorplans by dry weight, in a line that runs from 2,604 lbs to 11,327 lbs. It sits in the middle of the line by weight.

Plan the tow on loaded weight, not the 5,167 lbs dry figure: half the published cargo capacity brings this plan to about 5,435 lbs, and the published GVWR of 5,702 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. 17THHC is a Cascade designation and this site does not decode it into a layout claim.

How the 17THHC differs from the other fifteen Cascade floorplans. Most distinctive first. How these ranks are worked out.

• Cargo capacity, 535 lb: smallest of sixteen; next is the 17LPC (781 lb).
• Cargo capacity as a share of GVWR, 9.4%: smallest of sixteen; next is the 17MPHC (14.3%).
• Fresh tank, 13 gal: second-smallest of sixteen, between the 17MPHC (12 gal) and the 14BHLPC, 17LPC and two others (26 gal).
• Black tank, 4.5 gal: second-smallest of sixteen, between the 17MPHC (4 gal) and the 14BHLPC, 17LPC and three others (28 gal).
• Grey tank, 12 gal: smallest of sixteen, level with the 17MPHC; next are the 14BHLPC, 17LPC and two others (28 gal).
• GVWR, 5,702 lb: sixth-lowest of sixteen, between the 17MPHC (5,690 lb) and the 26LPC (7,560 lb).
• Dry weight, 5,167 lb: seventh-lightest of sixteen, between the 17MPHC (4,879 lb) and the 23MSC (5,948 lb).
• Tongue weight, 602 lb: seventh-lightest of sixteen, between the 17MPHC (590 lb) and the 26SSC (725 lb).
• Tongue weight as a share of dry weight, 11.7%: shared with the 26SSC; of sixteen, two smaller and twelve larger, nearest the 18PBC (10.7%) and the 39DLC (11.8%).
• Exterior height, 10 ft 4 in: shared with the 17MPHC and 18PBC; of sixteen, two lower and eleven taller, nearest the 14BHLPC (10 ft 2 in) and the 17SCC and 26KFC (10 ft 5 in).
• Length, 26 ft 8 in: shared with the 17MPHC; of sixteen, four shorter and ten longer, nearest the 17SCC and 18PBC (23 ft 11 in) and the 23MSC and 26LPC (29 ft 2 in).

Next to the 17MPHC, the nearest lighter floorplan by dry weight, the 17THHC is 288 lb heavier by dry weight, has a GVWR 12 lb higher, has 276 lb less cargo capacity, has a tongue weight 12 lb heavier, has a fresh tank 1 gal larger and has a black tank 0.5 gal larger; the two publish the same length, exterior height and grey tank.

Next to the 23MSC, the nearest heavier floorplan by dry weight, the 17THHC is 781 lb lighter by dry weight, has a GVWR 2,073 lb lower, has 1,292 lb less cargo capacity, has a tongue weight 173 lb lighter, is 2 ft 6 in shorter, stands 4 in lower, has a fresh tank 39 gal smaller, has a grey tank 26 gal smaller and has a black tank 33.5 gal smaller.

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 13-gallon fresh tank is about 108 lb of water (water counts as cargo: 49 CFR 571.110 S9.3.2), 20% of the 17THHC’s 535 lb cargo capacity, leaving 427 lb. Across 16 Cascade floorplans the water share runs 8% to 32%, and 6 give up more than this one. Nearest on that share: Cascade 18PBC at 19% and Cascade 301BHC at 22%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.110 S9.3.3).
