01 What makes it unique
The 31FKRK is the 26FKDS idea stretched. The Forest River factory describes the floorplan as two entries and two slide outs, with a metal exterior and a 21-foot awning, and an interior of a front kitchen and a rear bedroom — sleeping four in about 38 feet, one of the longest plans on the roster. The extra seven feet over the 26FKDS goes into the living space between the front galley and the rear bedroom rather than into berths, so it stays a four-sleeper: this is a couples trailer with a full-size kitchen, not a family bunkhouse. It carries the standard Puma build: a powder-coated steel I-beam frame with steel crossmembers under .024/.030-gauge aluminum skin, an AlphaPly roof membrane under a limited lifetime warranty, R-7 fiberglass insulation cut and glued between sidewall studs on 16-inch centres, a 5/8-inch Araucoply plywood floor under a 25-year limited warranty, an enclosed Darco-wrapped underbelly with enclosed water tanks, a tankless water heater and an 11 cu ft 12-volt refrigerator. Solar is roof and side-mount prep only — no panel is installed from the factory.
Palomino publishes a 9,930-pound GVWR against the 8,333-pound dry weight, leaving a 1,597-pound cargo capacity and a 1,130-pound dry tongue — the heaviest tongue of the eight profiled plans, again the signature of a front galley on a long body. The tank set is 43/65/30 gallons fresh/grey/black, and the 30-gallon black tank is the smallest on the whole Puma roster, which is worth knowing if you dry-camp for more than a long weekend. Palomino and Forest River publish no MSRP for the Puma line, so confirm street pricing with a dealer. The 31FKRK wants a well-rated half-ton at minimum and is happier behind a three-quarter-ton.
Forest River lists all four Puma packages as required, but the Value Shopper Package specifies a 13,500 BTU ducted air conditioner and the Limited Edition Package specifies a 15,000 BTU unit in place of it — the two required packages contradict each other, so confirm the air conditioner on the actual unit.

These graphics are generated from the same verified record that builds the table above, and are published under this site’s own licence — nothing here is traced from, or derived from, a manufacturer drawing or photo. Where a figure is not published for this plan, the graphic that would need it is omitted rather than estimated. The full record is in the published dataset.
What it takes to tow this
Built from this floorplan’s verified weights. We publish the trailer side only.
We do not publish tow ratings for specific trucks. A single model can vary by thousands of pounds depending on engine, axle ratio, cab, drivetrain and package — the only authoritative figure is the one on your own door jamb. Loaded tongue percentages are industry convention for travel trailers (10–15% of loaded weight), not a measurement of this unit. Hitch classes are not used here as a rating: SAE J684 covers trailers to 10,000 lb GVWR and does not define Class V, and capacity boundaries differ between manufacturers — read the rating stamped on your hitch. On this plan the convention band’s low end fell below the published dry figure, so the range starts at the published dry weight instead — loaded is never lighter than dry.
03 The Puma floorplan family
Puma is Palomino's metal-sided value travel trailer — bumper-pull towables on a powder-coated steel I-beam frame, and a cross-shop against Forest River's own Salem / Wildwood and Aurora, Prime Time's Avenger, Keystone's Springdale and Jayco's Jay Flight SLX. Eight floorplans are profiled in full and linked below; the remaining plans are catalogued and shown muted. The 31FKRK on this page is highlighted.
| Floorplan | Nominal | Sleeps | Notable |
|---|---|---|---|
| 220FK | 25 ft | — | Front kitchen and rear bathroom |
| 227RK | 26 ft | 4 | Rear kitchen, front bedroom and pass through bathroom |
| 229RB | 26 ft | 3 | Front bedroom and rear bathroom |
| 25BHS | 30 ft | 9 | Bunk beds and front bedroom |
| 26FKDS | 30 ft | 5 | Front kitchen and rear bedroom |
| 27RBDS | 33 ft | 4 | Front bedroom and rear bathroom |
| 290RL | 34 ft | — | Kitchen island, front bedroom and rear living |
| 310RK | 35 ft | 4 | Rear kitchen |
| 30RKQS | 36 ft | 4 | Rear kitchen and front bedroom |

Puma is Palomino's metal-sided value travel trailer — a powder-coated steel I-beam frame under .024/.030-gauge aluminum skin, and a cross-shop against Forest River's own Salem / Wildwood and Aurora, Prime Time's Avenger, Keystone's Springdale and Passport, Jayco's Jay Flight SLX and Coachmen's Catalina. The 2026 factory roster carries twenty travel-trailer plans; the eight highest-demand floorplans are profiled here in full and the remaining twelve are catalogued from published specifications below. Every Puma rides a bumper-pull tandem-axle chassis with an AlphaPly roof under a limited lifetime warranty, R-7 fiberglass sidewall insulation, an enclosed Darco-wrapped underbelly, a tankless water heater and an 11 cu ft 12-volt refrigerator, and every plan carries a 43-gallon fresh tank. Solar is prep only. Tongue weight, GVWR, dry weight and CCC are published per plan and each plan's dry weight plus CCC equals its GVWR exactly. Dry weight is a factory estimate; real loaded tongue weights run higher — always weigh the loaded trailer and confirm against your vehicle's tow rating and payload.
04 What owners & reviewers report
A full front galley on a 38-foot body
The factory floorplan lists a front kitchen and a rear bedroom on two slides with dual entry — the living space sits between them.
The heaviest tongue of the profiled plans
At 1,130 pounds dry the tongue is the heaviest of the eight profiled Pumas — check it against your vehicle's payload and use a weight-distributing hitch.
The smallest black tank on the roster
The 30-gallon black tank is the smallest of the twenty plans — a real constraint for extended dry camping with a full crew.
Confirm the air conditioner
The Value Shopper Package lists a 13,500 BTU ducted A/C and the Limited Edition Package lists a 15,000 BTU unit in place of it; Forest River marks both required, so confirm the size on the unit.
Weigh the loaded trailer
Dry weight is a factory estimate and real loaded tongue weights run above the 1,130-pound base — weigh the loaded trailer before you tow.
05 How it compares
The 26FKDS — the same front-kitchen and rear-bedroom layout about seven feet shorter and 1,280 pounds lighter dry.
Forest River's own Salem / Wildwood — the in-house metal-sided value cross-shop.
Keystone's Passport — a value-bracket cross-shop from the other volume builder.
06 Loading it for a trip
This floorplan carries its water comfortably. A full 43-gallon fresh tank is roughly 22% of the 1,597-pound cargo capacity, leaving the 31FKRK with a usable gear budget even when you tow full.
| Weight budget | Figure | What it means |
|---|---|---|
| Cargo capacity as published (CCC) | 1,597 lb | Everything you add: gear, water, propane, batteries, food, people’s belongings. |
| Fresh tank filled (43 gal × 8.34 lb) | −359 lb | Water is the heaviest thing most owners add, and it is added first. |
| Cargo budget left with a full fresh tank | 1,238 lb | 22% of this plan’s capacity is spent before a single bag is loaded. |
| Per sleeping position, water aboard | 310 lb | A rough share of what is left across the 4 berths this plan sleeps. |
The published dry tongue weight of 1,130 pounds is 14% of the 8,333-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 9,930-pound GVWR the 31FKRK is towing 1,597 pounds more than its 8,333-pound dry figure, and that is the number your vehicle has to be rated for — not the brochure weight.
Tank balance is generous here: 43 gallons of fresh against 65 grey and 30 black, so waste capacity keeps pace with supply and the fresh tank is the constraint that ends a dry stay.
07 Where this floorplan sits
Ranked by GVWR, the 31FKRK sits 6 of 33 in the Puma line: 9,930 pounds against a line that runs from 8,553 to 18,575 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: Puma 30RKQS is 330 pounds lighter at 9,600 lb GVWR; and Puma Ambush 27TH is 65 pounds heavier at 9,995 lb GVWR.
| Comparable travel trailers | GVWR (lb) | Dry (lb) | Sleeps | Length |
|---|---|---|---|---|
| 31FKRK | 9,930 | 8,333 | 4 | 37 ft 11 in |
| Westbrook Luxury 305DBLC | 9,925 | 8,008 | — | 37 ft 9 in |
| Momentum 17MAV | 9,950 | 5,542 | 2 | 22 ft 11 in |
| Rockwood & Flagstaff Ultra Lite 2918BH | 9,900 | 7,851 | 7 | 35 ft 5 in |
| Campsite Reserve 27MR | 9,985 | 7,243 | — | 34 ft 8 in |
| Coachmen Catalina 293TQBSCK | 9,868 | 7,868 | 10 | 36 ft 1 in |
| Cascade 29TEC | 9,995 | 6,943 | — | 36 ft 6 in |
Against the 31FKRK: the Westbrook Luxury 305DBLC is 5 lb lighter; the Momentum 17MAV is 20 lb heavier and 15 ft shorter and sleeps 2 fewer; the Rockwood & Flagstaff Ultra Lite 2918BH is 30 lb lighter and 2 ft shorter and sleeps 3 more. 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 Puma floorplans profiled here run 6,173 to 15,114 pounds dry and 30 to 43 feet of exterior length across 33 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 Puma line hub.
08 Common questions about the 31FKRK
How much does the 31FKRK weigh?
It leaves the factory at 8,333 pounds dry, and its manufacturer-set loaded ceiling (GVWR) is 9,930 pounds. Real towing weight lands between the two and depends entirely on what you load. Use the GVWR when matching a tow vehicle; the dry figure is only useful for comparing floorplans against each other.
How much can the 31FKRK carry?
Cargo carrying capacity is 1,597 pounds. That is the whole budget: water, propane, batteries, gear and everything you bring. Filling the 43-gallon fresh tank uses about 359 pounds of that.
What is the tongue weight of the 31FKRK?
The published dry tongue weight is 1,130 pounds. It is measured empty; loaded, it runs higher, and it comes out of your tow vehicle’s payload rather than its tow rating.
What size tow vehicle does the 31FKRK need?
Your vehicle needs a tow rating of at least 9,930 pounds — this floorplan’s GVWR — and enough payload left over for the hitch load, passengers and anything in the bed. This site does not publish tow ratings for specific vehicles, because one truck model varies by thousands of pounds across engine, axle ratio, cab and package. The figure that governs is the payload sticker on your own door jamb.
How many people does the 31FKRK sleep?
It is rated to sleep 4. Rated sleeping positions include convertible furniture, so count the beds against how you actually travel rather than against the number.
What are the tank capacities on the 31FKRK?
Fresh 43 gallons, grey 65 gallons, black 30 gallons. Tank sizes set how long the floorplan can sit away from hookups, and the smallest of the three is what ends the stay.
How long is the 31FKRK?
Exterior length is 37' 11". Measure against your site length and your storage before committing — the exterior figure is the one that has to fit, and it includes the tongue or pin box.
Every figure in these answers is read from this page’s verified specification table. Where the manufacturer publishes nothing, the question is not answered rather than estimated.
09 What this page publishes, and what it does not
This catalog tracks 18 specification fields per floorplan. Named sources publish 16 of them for the 31FKRK. 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, tire specification. 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 (94%) 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.
Values on this page carrying an asterisk were derived by arithmetic from published figures, or come from a single source, rather than being printed directly by the manufacturer. The flag travels with the number into the downloadable spec sheet.
How every figure here was sourced and checked is set out on the methodology page.
11 NHTSA safety record
This floorplan belongs to the Puma line, and NHTSA holds 21 recall campaigns and 39 owner complaints against that line. They are separate records and are not added together — a recall is a manufacturer-confirmed defect with a remedy; a complaint is one owner’s account, which NHTSA does not verify.
What to look at on a used one. Across the 39 complaints filed on this line the most-reported components are tires (28%), structure (21%) and equipment (15%). That is where owners of this family have had trouble, so it is where an inspection is worth the time.
Recall coverage is not complete — our harvest of NHTSA’s recall API ran 1,556 queries, of which 0 failed and 242 returned an explicit zero. A line can still be under-reported where NHTSA files a roster under a parent name, or where a match rests on the wording of the recall rather than its model field. Complaints come from the complete bulk file but are unverified and self-selected: a high count tracks how many units a line sold at least as much as how well it was built. Check a specific VIN at NHTSA before you buy. Full tables are on the Puma line page.
