2026 Palomino Puma310RK

The 310RK is the easiest-towing long Puma. The Forest River factory describes the floorplan as one entry and two slide outs, with a metal exterior and a 21-foot awning, and an interior of a rear kitchen — sleeping four in about 35½ feet. The factory sentence names only the rear kitchen, which sets it apart from the 30RKQS: it is the plainest of the rear-galley plans and the one that leans hardest on the galley itself. It also stands 11 feet 3 inches tall, two inches above the 11-foot-1 line norm and worth a note if you have a tight garage or a low overhang. 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 9,263-pound GVWR against the 7,763-pound dry weight, leaving a 1,500-pound cargo capacity and an 840-pound dry tongue. That tongue is the story: it is more than 200 pounds lighter than the 30RKQS's, on a trailer only six inches shorter and 211 pounds lighter dry, which makes the 310RK meaningfully easier on a half-ton's payload than the rest of the long Pumas. The tank set is 43/70/35 gallons fresh/grey/black. Palomino and Forest River publish no MSRP for the Puma line, so confirm street pricing with a dealer. The 310RK is the Puma for a couple who wants a rear galley and the friendliest tongue weight in the long half of the roster.

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.

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 310RK on this page is highlighted.

This floorplan carries its water comfortably. A full 43-gallon fresh tank is roughly 24% of the 1,500-pound cargo capacity, leaving the 310RK with a usable gear budget even when you tow full.

The published dry tongue weight of 840 pounds is 11% of the 7,763-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 9,263-pound GVWR the 310RK is towing 1,500 pounds more than its 7,763-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 70 grey and 35 black, so waste capacity keeps pace with supply and the fresh tank is the constraint that ends a dry stay.

Ranked by GVWR, the 310RK sits 3 of 33 in the Puma line: 9,263 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 Ambush 25TH is 390 pounds lighter at 8,873 lb GVWR; and Puma 337BH matches it exactly at 9,263 lb GVWR.

1 other Puma plan shares this floorplan’s 9,263 lb GVWR, so the ranking above separates plans that tow to the same ceiling. On a shared chassis the figure that actually differs between them is cargo capacity and where the weight sits, not the rating.

Against the 310RK: the Coachmen Catalina 293QBCK is 1 lb heavier and 2 ft shorter and sleeps 2 more; the Delta 294RK is 13 lb lighter and 2 ft shorter; the Airelume 285 is 30 lb lighter and 1 ft longer. 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.

This catalog tracks 18 specification fields per floorplan. Named sources publish 16 of them for the 310RK. 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.
