A rear-kitchen fifth wheel puts the kitchen at the back of the trailer. This guide covers 12 floor plans for 2027 that Forest River and Keystone describe this way, across eight lines, from the 29-foot-4-inch Rockwood Signature 281SRK and Flagstaff Classic 281CRK to the 43-foot-10-inch Montana 3900RK, with published hitch weights of 1,280 to 3,405 pounds.
At a glance
- The Forest River plans in this guide are the Rockwood Signature 281SRK, 301SRK and 404SRK, their Flagstaff Classic twins (281CRK, 301CRK and 404CRK) and the Wildcat 33CHEF.
- The Keystone plans are the Cougar Half-Ton 29MBD, Cougar 350LLK, Montana High Country 300RK, Alpine 3910RK and Montana 3900RK.
- The Cougar Half-Ton 29MBD is the only plan here whose layout description includes a bunk, and Keystone lists it as sleeping 10; the other Keystone plans sleep four or six.
- The Rockwood Signature 301SRK and Flagstaff Classic 301CRK have the lowest published unloaded weight in this guide, 7,523 pounds, and the Montana 3900RK the highest shipping weight, 17,085 pounds.
- On 29 October 2026, the median asking price of new listings on Searchshop ran from $56,995 for the Cougar Half-Ton 29MBD to $93,992 for the Alpine 3910RK.
Only floor plans that the manufacturer itself describes in words as a rear kitchen are included, read from Forest River's and Keystone's own floor plan pages on 29 October 2026. All of those pages are for 2027 models. Figures are the makers' published specifications; no trailer was inspected or towed for this guide.
Forest River plans were found by searching Forest River's site, and Forest River builds other fifth wheel lines not covered here. Keystone's 2027 Cougar Sport and Arcadia Select fifth wheel pages list no plan described as a rear kitchen. A floor plan code is not enough on its own: some 2027 fifth wheels with "RK" in their names, such as Jayco's Eagle SLE 28RKS, Grand Design's Solitude 390RK and Forest River's Sierra 3800RK, have no layout description on the pages read for this guide, so they are left out. Check the floor plan drawing of any trailer you are considering. Keystone also lists a Cougar Half-Ton 29RKS as dealer stock only, and a Montana High Country 362BRK with no published weight or length, so neither is in the tables.
The two makers do not use the same weight terms. Forest River lists unloaded vehicle weight (UVW), which it defines as the typical weight of the unit as built at the factory, including LP gas but not cargo, fresh water, additional optional equipment or dealer-installed accessories. Keystone lists a shipping weight and a carrying capacity. Because the terms differ, each brand has its own table below.
A rear-kitchen fifth wheel moves the kitchen to the back wall, and the makers' descriptions show what usually fills the rest of the trailer. Forest River describes the Rockwood Signature 281SRK and 301SRK with a living area of 67-inch theater seating facing a fireplace and entertainment center, "flexible dining" with a table, chairs and bench, and a private front bedroom with a king bed and washer and dryer prep.
The larger 404SRK and 404CRK are described as wide-body rear-kitchen plans with "expansive counter space, residential style appliances, and abundant storage," a mid living area with an L-shaped sofa and a 52-inch theater seat, and a private front bedroom with a king bed. Forest River says the Wildcat 33CHEF is a rear-kitchen floor plan "perfect for couples who love to cook and need space to work remotely."
Keystone sums up each plan in a short line. The Cougar Half-Ton 29MBD is "Rear Kitchen, Mid Bunk with King Master Bed," the Cougar 350LLK "Luxury Rear Kitchen, L-Sofa with Recliners," the Montana High Country 300RK "Rear Kitchen, Three Slides, L-Shaped Sofa," the Alpine 3910RK "Rear Kitchen, 1-1/2 bath, Front Bath, Master Suite" and the Montana 3900RK "Rear Kitchen, Four Slides, Master Suite."
For the layout that puts the living room in the raised front section instead, see front living fifth wheel layouts explained.
The seven Forest River rear-kitchen floor plans in this guide run from 29 feet 4 inches to 41 feet 5 inches, with unloaded weights of 7,523 to 11,804 pounds.
| Floor plan (2027) | Length | UVW | Hitch weight |
|---|
| Rockwood Signature 281SRK / Flagstaff Classic 281CRK | 29 ft 4 in | 7,733 lb | 1,280 lb |
| Rockwood Signature 301SRK / Flagstaff Classic 301CRK | 31 ft 8 in | 7,523 lb | 1,300 lb |
| Wildcat 33CHEF | 38 ft 3 in | 10,558 lb | 1,885 lb |
| Rockwood Signature 404SRK / Flagstaff Classic 404CRK | 41 ft 5 in | 11,804 lb | 2,205 lb |
Each Rockwood Signature plan has a Flagstaff Classic twin: the 281SRK and 281CRK, the 301SRK and 301CRK, and the 404SRK and 404CRK have nearly identical descriptions and the same length, height, UVW, hitch weight and tank sizes on Forest River's pages. For how the two sister lines relate across the rest of their range, see Rockwood vs Flagstaff.
Forest River lists a cargo carrying capacity of 2,142 pounds for the 281SRK and 281CRK, 2,440 pounds for the 301SRK and 2,401 pounds for the 404SRK and 404CRK. The Wildcat 33CHEF lists 3,327 pounds of cargo capacity and a GVWR of 13,885 pounds. The 301CRK page lists a cargo capacity equal to its UVW, 7,523 pounds, so that figure is left out here; check the label on the trailer.
Forest River's tank sizes follow the twins. The 281 and 301 twins list 54 gallons of fresh water, 78 gray and 39 black; the 404SRK and 404CRK list 54 fresh, 92 gray and 53 black; and the Wildcat 33CHEF lists 60 fresh, 76 gray and 38 black. Forest River names an 11 cubic foot refrigerator in the 281 and 301 descriptions.

The five Keystone rear-kitchen floor plans in this guide run from 33 feet 11 inches to 43 feet 10 inches, with shipping weights of 9,325 to 17,085 pounds.
| Floor plan (2027) | Length | Shipping weight | Hitch weight |
|---|
| Cougar Half-Ton 29MBD | 33 ft 11 in | 9,325 lb | 1,635 lb |
| Montana High Country 300RK | 34 ft 11 in | 12,540 lb | 2,055 lb |
| Cougar 350LLK | 39 ft 3 in | 12,040 lb | 2,240 lb |
| Alpine 3910RK | 42 ft 10 in | 14,640 lb | 2,980 lb |
| Montana 3900RK | 43 ft 10 in | 17,085 lb | 3,405 lb |
Keystone lists sleeping capacity of 10 for the 29MBD, six for the Alpine 3910RK and four for the 300RK, 350LLK and 3900RK. Carrying capacity is 2,175 pounds on the 29MBD, 3,160 pounds on the 300RK, 2,960 pounds on the 350LLK, 3,360 pounds on the 3910RK and 2,320 pounds on the 3900RK.
Keystone's tank sizes vary widely across these plans. The 29MBD lists 60 gallons of gray water, the 350LLK 76, the 3910RK 83, the 300RK 100 and the 3900RK 150. Fresh water is 77 gallons on the 300RK and 3900RK. Keystone's pages give two different fresh tank sizes for the 29MBD and the 350LLK, and two black tank sizes for the 3910RK, so those figures are left out. Keystone's specification tables list a 10.6 cubic foot refrigerator in the 29MBD, 16 cubic feet in the 350LLK and 300RK, and 20 cubic feet in the 3900RK.
In the Montana line, the rear kitchen is the biggest plan. Keystone's five 2027 Montana floor plans weigh 14,930 to 17,085 pounds, and the 3900RK is both the longest and the heaviest of them. For every Cougar layout, including the rear-kitchen plans, see the Keystone Cougar floor plans guide.
New rear-kitchen fifth wheels listed on Searchshop had median asking prices of $56,995 to $93,992 on 29 October 2026, for the five floor plans with at least five priced listings.
| Floor plan | New listings | Model years listed | Median asking price |
|---|
| Cougar Half-Ton 29MBD | 17 | 2026 | $56,995 |
| Cougar 350LLK | 10 | 2026 and 2027 | $74,950 |
| Rockwood Signature 404SRK | 9 | 2026 and 2027 | $82,747 |
| Flagstaff Classic 404CRK | 5 | 2026 and 2027 | $82,747 |
| Alpine 3910RK | 10 | 2025 and 2026 | $93,992 |
Counts are new listings in Searchshop's RV feed whose title or floor plan field named that floor plan code and that showed an asking price. Most are 2026 or 2025 models, so their specifications can differ from the 2027 pages above. Asking prices are what dealers advertise, not sale prices, and exclude taxes and fees. The other floor plans in this guide had fewer than five matching listings, so no median is given for them.
A rear-kitchen fifth wheel's hitch weight sits on your truck's bed, so the truck's payload has to cover it along with people and cargo. The plans in this guide publish hitch weights from 1,280 pounds on the 281SRK and 281CRK to 3,405 pounds on the Montana 3900RK.
Published figures describe the trailer as the maker lists it. Forest River's UVW excludes cargo, fresh water, additional optional equipment and dealer-installed accessories, and Keystone tells owners to read the labels on each trailer for its actual weights and cargo carrying capacity. Compare the label figures on the trailer you are buying against the payload sticker on your truck's door, then weigh the loaded rig. The fifth wheel towing guide walks through that check step by step.
A rear-kitchen fifth wheel suits buyers who want the kitchen as a separate end of the trailer, and the published figures point to three groups of buyers.
- Couples: four of the five Keystone plans here sleep four or six, and Forest River describes the 281SRK, 301SRK and 404SRK with a private front bedroom.
- Families: the Cougar Half-Ton 29MBD is the only plan in this guide whose layout description includes a bunk, and Keystone lists it as sleeping 10.
- Longer stays between dump stops: the Montana 3900RK lists 150 gallons of gray water and 100 of black, the largest tanks among these plans, and the Alpine 3910RK adds a half bath.
Shoppers who want a lighter trailer can start with the Forest River 281 and 301 twins, which publish unloaded weights under 7,800 pounds. Shoppers who mostly want room to cook can compare the 404SRK and 404CRK, the Wildcat 33CHEF and the Cougar 350LLK, whose makers single out the kitchen in their descriptions.
Narrow the list by the truck you have, then by how many people sleep aboard, and then by tank size and kitchen features.
- Rule out any plan whose published hitch weight your truck's payload cannot cover with people and cargo aboard.
- Choose the 29MBD if you need bunks; otherwise compare the four- and six-sleeper plans.
- Check the floor plan drawing and the trailer's own weight label before you buy, because codes and figures change between model years.
- Compare asking prices for the same floor plan across dealers, and ask each for an out-the-door figure.

No, a model code does not reliably tell you where the kitchen is. The Forest River 281SRK, 301SRK and 404SRK and the Keystone 300RK, 3910RK and 3900RK are described as rear kitchens, but so are the Cougar 29MBD, Cougar 350LLK and Wildcat 33CHEF, which have no "RK" in their names. Several other 2027 plans with "RK" in the code have no layout description on their makers' pages. Always check the floor plan drawing.
Among the 2027 plans in this guide, the Rockwood Signature 301SRK and Flagstaff Classic 301CRK publish the lowest unloaded weight, 7,523 pounds, with a 1,300-pound hitch weight. The lightest Keystone rear-kitchen plan is the Cougar Half-Ton 29MBD at a 9,325-pound shipping weight. The two brands use different weight terms, and the trailer's own label gives its actual weight.
Yes, the Keystone Cougar Half-Ton 29MBD pairs a rear kitchen with a mid bunk room. Keystone describes it as "Rear Kitchen, Mid Bunk with King Master Bed" and lists it as sleeping 10. It is 33 feet 11 inches long, with a 9,325-pound shipping weight and a 1,635-pound hitch weight. It is the only plan in this guide whose layout description includes a bunk.
Dealers' asking prices for new rear-kitchen fifth wheels on Searchshop had medians of $56,995 for the Cougar Half-Ton 29MBD, $74,950 for the Cougar 350LLK, $82,747 for the Rockwood Signature 404SRK and Flagstaff Classic 404CRK, and $93,992 for the Alpine 3910RK on 29 October 2026. Most of those listings are 2026 models, and prices exclude taxes and fees.
