2027 Forest River Rockwood Signature Fifth Wheels404SRK

The Rockwood Signature Fifth Wheels 404SRK leaves Forest River's factory at 11,804 lbs dry with 2,401 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 54-gallon fresh tank spends 448 lbs of the 2,401 lbs before anything else goes in.

Dry pin weight is 2,205 lbs, which is 19% of the dry weight. That figure lands on the truck's rear axle and comes straight off its payload rating - not its towing rating, which is the number most often quoted and the wrong one for this decision. Pin weight rises as the trailer is loaded, and a fifth wheel loaded toward its cargo capacity will put substantially more than 2,205 lbs over the bed. Read the payload figure on your own door sticker rather than a brochure maximum for the model.

Tank capacities are 54 gallons fresh, 92 grey and 53 black, 145 gallons of waste capacity against 54 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 Rockwood Signature Fifth Wheels roster this is the 9th of 11 floorplans by dry weight, in a line that runs from 7,523 lbs to 12,824 lbs. It sits in the heavier 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 these figures is to stop planning against the dry weight. Nobody tows a trailer at 11,804 lbs: that is the weight before water, batteries, propane, bedding, food, tools and anything the dealer bolted on. Load half the published cargo capacity and this plan is already near 13,004 lbs on the road. Because Forest River publishes no loaded rating for this line, the ceiling has to come from the trailer's own weight label rather than from this page, and the comparison you make against the tow vehicle should use the loaded figure.

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. There is no published GVWR on this line, so the usual arithmetic check - dry plus cargo equals the rating - has nothing to test against here. 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's own description of this floorplan reads: “This Wide Body fifth wheel is a rear kitchen layout features expansive counter space, residential style appliances, and abundant storage, making it ideal for those who love to cook while traveling. The mid living area features an L-shaped sofa with an integrated Hide-a-bed and 52" theater seat that requires no dismantling when the slides are retracted. Up front you have a private bedroom with a king bed and generous…” That is the factory's marketing copy rather than a specification, and nothing in it is treated as a verified field on this page - layout descriptions, sleeping arrangements and feature claims in factory copy are not carried into the spec table unless the factory also publishes them as specifications.

Signature is where Rockwood stops being a bumper-pull range. Across the ten plans profiled here dry weight runs 7,733 to 12,824 lb and dry pin weight runs 1,280 to 2,205 lb, which is a payload question before it is a towing one -- pin weight lands on the truck's rear axle, and the heavier plans ask for more of it than most half-ton payload ratings have left once passengers and a hitch are in. Pin sits in a tight band of 16.6 to 19.3 percent of dry weight across the whole roster, so the grouping scales predictably rather than hiding a nose-heavy outlier. Cargo capacity runs 1,461 to 2,674 lb and does not track size: the heaviest plan carries the most, but the second-least accommodating plan is a mid-weight one, so the spread is worth reading per plan rather than by length. Fresh water is 54 gallons on every plan in the roster; grey runs 78 to 131 gallons and black 39 to 92, so waste capacity is the variable that separates these plans off-grid, not fresh.

This floorplan carries its water comfortably. A full 54-gallon fresh tank is roughly 19% of the 2,401-pound cargo capacity, leaving the 404SRK with a usable gear budget even when you tow full.

The published dry pin weight of 2,205 pounds is 19% of this floorplan’s 11,804-pound dry weight. Fifth-wheel pin weight rides in the bed of the truck, so it comes off payload rather than off tow rating — and it rises with the trailer as you load it, not in proportion to what you put over the axles.

Tank balance is generous here: 54 gallons of fresh against 92 grey and 53 black, so waste capacity keeps pace with supply and the fresh tank is the constraint that ends a dry stay.

Ranked by dry weight, the 404SRK sits 8 of 10 in the Rockwood Signature Fifth Wheels line: 11,804 pounds against a line that runs from 7,733 to 12,824 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: Rockwood Signature Fifth Wheels 401SFB is 344 pounds lighter at 11,460 lb dry; and Rockwood Signature Fifth Wheels 402SFL is 185 pounds heavier at 11,989 lb dry.

Against the 404SRK: the Influence 2903RL is 4 lb lighter and 7 ft shorter; the Impression 36BR3 is 16 lb lighter; the Model Z 2810 is 90 lb heavier and 7 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 fifth wheels 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 Rockwood Signature Fifth Wheels floorplans profiled here run 7,733 to 12,824 pounds dry and 29 to 41 feet of exterior length across 10 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.

This catalog tracks 18 specification fields per floorplan. Named sources publish 10 of them for the 404SRK. 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: GVWR, interior height, sleeps, slide count, axle count, tire specification, 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 (83%) 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.
