01 What makes it unique
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.
Pin weight is 2,205 lbs, 19% of the dry weight as published; it rises as the trailer is loaded and comes off the truck’s payload, not its towing rating, so check it against the payload on your own door sticker (pin weight and payload).
Off hookups: 145 gallons of grey and black capacity against 54 gallons of fresh water, so fresh water runs out first (tank sizes by length).
Against the rest of the Rockwood Signature Fifth Wheels roster this is the 17th of 19 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.
Plan the tow on loaded weight, not the 11,804 lbs dry figure: half the published cargo capacity brings this plan to about 13,004 lbs. Forest River publishes no loaded rating for this line, so the ceiling is the one on the trailer’s own weight label (how to read trailer weights).
Forest River’s line listing and this floorplan’s own factory page agree on all 4 shared figures. No GVWR is published for this line, so dry plus cargo has no rating to check against. A missing row means Forest River does not publish that figure (how figures are verified).
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.
How the 404SRK differs from the other eighteen Rockwood Signature Fifth Wheels. Most distinctive first. Sibling pages may cover other model years than this one (2027). How these ranks are worked out.
- Pin weight, 2,205 lb: heaviest of nineteen; next is the 403SDB (2,190 lb).
- Dry weight, 11,804 lb: third-heaviest of nineteen, between the 401SFB (11,460 lb) and the 402SFL (11,989 lb).
- Cargo capacity, 2,401 lb: third-largest of nineteen, between the R361RLS (2,197 lb) and the 301SRK (2,440 lb).
- Length, 41 ft 5 in: longest of nineteen, level with the 403SDB; next are the 401SFB and 402SFL (40 ft).
- Pin weight as a share of dry weight, 18.7%: shared with the 290SFK; of nineteen, sixteen smaller and one larger, nearest the R361RLS (18.2%) and the R371RK (19.3%).
- Grey tank, 92 gal: shared with the R361RLS, R371RK and R374DBH; of nineteen, twelve smaller and three larger, nearest the 8291RK, 8298KS and 8299SB (90 gal) and the 290SFK (108 gal).
- Exterior height, 13 ft 4 in: shared with the 401SFB, R361RLS and three others; of nineteen, eleven lower and two taller, nearest the 290SFK (13 ft 3 in) and the 402SFL and 403SDB (13 ft 5 in).
- Black tank, 53 gal: shared with the 402SFL, R361RLS and three others; of nineteen, eleven smaller and two larger, nearest the 8288SB, 8291RK and three others (50 gal) and the 401SFB and 403SDB (92 gal).
Next to the 401SFB, the nearest lighter floorplan by dry weight, the 404SRK is 344 lb heavier by dry weight, has 365 lb more cargo capacity, has a pin weight 126 lb heavier, is 1 ft 5 in longer, has a grey tank 9 gal larger and has a black tank 39 gal smaller; the two publish the same exterior height and fresh tank.
Next to the 402SFL, the nearest heavier floorplan by dry weight, the 404SRK is 185 lb lighter by dry weight, has 245 lb more cargo capacity, has a pin weight 60 lb heavier, is 1 ft 5 in longer, stands 1 in lower and has a grey tank 39 gal smaller; the two publish the same fresh tank and black tank.

03 The Rockwood Signature Fifth Wheels floorplan family
Signature is where Rockwood stops being a bumper-pull range. Across the fourteen plans profiled here dry weight runs 7,523 to 12,824 lb and 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 once passengers and a hitch are in. Pin sits in a band of 15.4 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 53 or 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.

Signature is the only Rockwood grouping built as a fifth wheel, and Forest River publishes fourteen floorplans for 2027 under two headings: nine as Signature Fifth Wheels and five as Signature Traveler Series Fifth Wheels, the lighter group at 7,523 to 9,762 lb dry against 8,764 to 12,824 lb. Every plan in the roster publishes dry weight, cargo capacity, pin weight, all three exterior dimensions and all three tank capacities, and thirteen of the fourteen carry a factory floorplan description. No plan publishes a GVWR, so loaded rating is shown as not published throughout and is never derived from dry weight plus cargo capacity. Sleeping capacity, axle count, tire size and MSRP are not published in this channel either, and are absent rather than estimated. Two cargo figures changed on Forest River's own floorplan pages between this site's readings of 31 Jul and 21 Oct 2026: the 301SRK's moved from 7,523 lb, the same figure to the pound as its dry weight, to 2,440 lb, and the R361RLS's from 1,730 lb to 2,197 lb. Both plans are profiled from the revised figures, and the earlier ones are not used.
04 Notes on this floorplan
What Forest River does not publish for this line
Sleeping capacity, axle count, tire size and MSRP are absent from Forest River's specification channel for Rockwood Signature Fifth Wheels, so they are absent here. They are not estimated from the segment, not carried over from a sibling floorplan, and not taken from a dealer listing quoting itself. A tire size in particular is a safety-relevant number that differs between two codes a digit apart, and this site does not guess one.
There is no factory GVWR for this trailer
Forest River publishes dry weight, cargo capacity and pin weight for every Rockwood Signature Fifth Wheels floorplan and publishes no GVWR for any of them. The factory's own glossary defines cargo capacity as GVWR minus UVW, which means the rating can be worked out - and a figure you worked out is not a figure the manufacturer published, so this page does not print one. Use the weight label on the trailer itself, which every Forest River unit carries.
Weigh it before you tow it
Forest River calls its unloaded weight an estimated average for a standard build, and options and dealer add-ons change it, so weigh your own trailer loaded the way you travel (how figures are verified).
05 How it compares
11,460 lbs dry against this plan's 11,804 lbs, a difference of 344 lbs.
11,989 lbs dry, 185 lbs more than this plan, and 2,156 lbs of cargo capacity against this one's 2,401 lbs.
2,674 lbs of cargo capacity, the highest of the 19 Rockwood Signature Fifth Wheels floorplans profiled here. If payload rather than length is the binding constraint, that is the plan to compare against.
06 Loading it for a trip
A full 54-gallon fresh tank is about 448 lb of water, 19% of the 404SRK’s 2,401 lb cargo capacity, leaving 1,953 lb. Across 19 Rockwood Signature Fifth Wheels floorplans the water share runs 17% to 31%, and 16 give up more than this one. Nearest on that share: Rockwood Signature Fifth Wheels 301SRK at 18% and Rockwood Signature Fifth Wheels R361RLS at 20%.
07 Where this floorplan sits
Closest sibling: the Rockwood Signature Fifth Wheels R361RLS, nearest on the published figures. It differs on 4 of the 7 fields both publish (this plan first): length 41 ft 5 in vs 36 ft 10 in; dry weight 11,804 lb vs 10,601 lb; cargo capacity 2,401 lb vs 2,197 lb; hitch weight 2,205 lb vs 1,931 lb. They match on fresh tank, grey tank and black tank.
