2027 Forest River Rockwood Signature Fifth Wheels401SFB

The Rockwood Signature Fifth Wheels 401SFB leaves Forest River's factory at 11,460 lbs dry with 2,036 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 2,036 lbs before anything else goes in.

Pin weight is 2,079 lbs, 18% 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: 175 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 16th 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 11,460 lbs dry figure: half the published cargo capacity brings this plan to about 12,478 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: “Discover comfort and style in the Rockwood 401SFB fifth wheel-designed for unforgettable travel. This bath and a half floorplan offers a spacious rear living area with theater seating and entertainment center, a well-appointed kitchen with island, a private king size bedroom, and sleek bathroom. With multiple slide outs, residential-style touches, and quality construction throughout, the 401SFB delivers space,…” 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 401SFB 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.

• Dry weight, 11,460 lb: fourth-heaviest of nineteen, between the R372RL (10,844 lb) and the 404SRK (11,804 lb).
• Pin weight, 2,079 lb: fourth-heaviest of nineteen, between the R371RK (2,001 lb) and the 402SFL (2,145 lb).
• Black tank, 92 gal: largest of nineteen, level with the 403SDB; next are the 402SFL, 404SRK and four others (53 gal).
• Length, 40 ft: shared with the 402SFL; of nineteen, fifteen shorter and two longer, nearest the 8298KS (37 ft 2 in) and the 403SDB and 404SRK (41 ft 5 in).
• Cargo capacity, 2,036 lb: eighth-smallest of nineteen, between the 8299SB (2,015 lb) and the 332SRL (2,046 lb).
• Pin weight as a share of dry weight, 18.1%: shared with the R374DBH; of nineteen, thirteen smaller and four larger, nearest the 402SFL (17.9%) and the R361RLS (18.2%).
• Exterior height, 13 ft 4 in: shared with the 404SRK, 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).
• Grey tank, 83 gal: shared with the R372RL; of nineteen, seven smaller and ten larger, nearest the 8288SB and 8294BS (80 gal) and the 8291RK, 8298KS and 8299SB (90 gal).

Next to the R372RL, the nearest lighter floorplan by dry weight, the 401SFB is 616 lb heavier by dry weight, has 575 lb more cargo capacity, has a pin weight 174 lb heavier, is 3 ft 2 in longer and has a black tank 39 gal larger; the two publish the same exterior height, fresh tank and grey tank.

Next to the 404SRK, the nearest heavier floorplan by dry weight, the 401SFB is 344 lb lighter by dry weight, has 365 lb less cargo capacity, has a pin weight 126 lb lighter, is 1 ft 5 in shorter, has a grey tank 9 gal smaller and has a black tank 39 gal larger; the two publish the same exterior height and fresh tank.

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.

A full 54-gallon fresh tank is about 448 lb of water, 22% of the 401SFB’s 2,036 lb cargo capacity, leaving 1,588 lb. Across 19 Rockwood Signature Fifth Wheels floorplans the water share runs 17% to 31%, and 7 give up more than this one. Nearest on that share: Rockwood Signature Fifth Wheels R371RK at 22% and Rockwood Signature Fifth Wheels 8299SB at 22%.
