2026 Forest River Cascade17MPHC

The Cascade 17MPHC leaves Forest River's factory at 4,879 lbs dry, with a published GVWR of 5,690 lbs and 811 lbs of cargo capacity between the two. Cargo capacity is 14% of the loaded rating, and Forest River's own definition is worth reading before you plan against it: cargo capacity is what remains for fresh water, gear, food, batteries and every dealer-installed accessory. Fresh water alone is 8.3 lb per gallon, so filling this trailer's 12-gallon fresh tank spends 100 lbs of that 811 lbs before anything else is loaded.

Dry tongue weight is 590 lbs, or 12% of the dry weight. Ten to fifteen percent is the conventional band for a bumper-pull trailer, and this plan sits inside it as published. Tongue weight is not fixed: it moves with how the trailer is loaded, and weight added ahead of the axles raises it. A weight-distribution hitch is the normal fitment at this tongue load, and the tow vehicle's tongue-weight limit is a separate number from its trailer-weight limit.

Tank capacities are 12 gallons fresh, 12 grey and 4 black, 16 gallons of waste capacity against 12 gallons of supply. The ratio is what governs how long the trailer can sit off hookups: waste capacity exceeds fresh, so the fresh tank is the binding constraint and refilling extends the stay. Forest River publishes these three figures per floorplan, and they are the factory's numbers rather than a segment average.

Against the rest of the Cascade roster this is the 6th of 20 floorplans by dry weight, in a line that runs from 2,604 lbs to 11,327 lbs. It sits in the lighter third of the line. Comparing floorplans inside one line is more reliable than comparing across brands, because every figure here comes from the same factory channel on the same day.

A useful way to read the pair of weights is to stop planning against the dry figure. Nobody tows a trailer at 4,879 lbs: that is the weight before water, batteries, propane, bedding, food, tools and anything the dealer bolted on. Load half the published cargo capacity, which is modest for a family trip, and this plan is already near 5,285 lbs on the road. Compare that number against the tow vehicle, not the dry weight, and leave margin on top of it - the published GVWR of 5,690 lbs is a limit rather than a target.

Every number above was captured twice from Forest River and checked against itself before it was published. The line roster block and the individual floorplan page are two separate factory renderings of the same trailer, and this plan's 4 shared figures agree exactly on both. Dry weight plus cargo capacity also equals the published GVWR exactly, which is the arithmetic check this site runs on every profiled floorplan. Where a figure is missing from this page it is because Forest River does not publish it in this channel, not because it was hard to find - and the row says so rather than being quietly dropped.

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. 17MPHC is a Cascade designation and this site does not decode it into a layout claim.

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. Dry 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.

This floorplan carries its water comfortably. A full 12-gallon fresh tank is roughly 12% of the 811-pound cargo capacity, leaving the 17MPHC with a usable gear budget even when you tow full.

The published dry tongue weight of 590 pounds is 12% of the 4,879-pound dry weight, which sits inside the 10–15% band usually quoted for stable towing. It is still a dry figure: loading the front pass-through and the fresh tank both push it up.

Nothing above changes the ceiling. Loaded to its 5,690-pound GVWR the 17MPHC is towing 811 pounds more than its 4,879-pound dry figure, and that is the number your vehicle has to be rated for — not the brochure weight.

Tank balance is generous here: 12 gallons of fresh against 12 grey and 4 black, so waste capacity keeps pace with supply and the fresh tank is the constraint that ends a dry stay.

Ranked by GVWR, the 17MPHC sits 5 of 16 in the Cascade line: 5,690 pounds against a line that runs from 3,820 to 13,342 pounds. That position is the useful thing to know, because the plans immediately either side of it are the real alternatives.

Either side of it in the same line: Cascade 18PBC is 115 pounds lighter at 5,575 lb GVWR; and Cascade 17THHC is 12 pounds heavier at 5,702 lb GVWR.

Against the 17MPHC: the Puma Camping Edition 20RLCE is 2 lb lighter and 2 ft shorter; the Surveyor Legend 19MDBLE is 8 lb heavier and 3 ft shorter; the Cherokee Wolf Pup 17JW is 17 lb heavier and 3 ft shorter. Those are differences in the published numbers only — what they cost, how they are built and how they live are separate questions each of those pages answers on its own terms.

Those are the nearest travel trailers from other lines by weight — one per line, picked by proximity on that figure and nothing else. They are listed so the same tow vehicle can be checked against real alternatives, not because they are equivalent inside; layout, build and price diverge sharply across that group.

For scale, the Cascade floorplans profiled here run 2,604 to 11,327 pounds dry and 17 to 43 feet of exterior length across 16 plans. Where a floorplan falls in that spread usually says more about which vehicle can tow it, and which site it fits, than the layout name does.

Every profiled floorplan in this line, with the full weight table, is on the Cascade line hub.

This catalog tracks 18 specification fields per floorplan. Named sources publish 10 of them for the 17MPHC. The rest are not shown, because the alternative is reading a figure across from a sibling floorplan or from what the segment usually does — and a number nobody published is worth less than an admitted gap.

Not published for this floorplan: interior height, sleeps, slide count, axle count, tire specification, awning, refrigerator, air conditioning. If you find one of these in a manufacturer document for this plan, it belongs on this page.

The completeness figure at the foot of this page (77%) measures the same thing on the full field set: it is a measurement of how much this floorplan’s manufacturer publishes, not of how much research went into the page.

How every figure here was sourced and checked is set out on the methodology page.
