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.

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.

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.
