2026 PalominoPuma Mesa 379MBL

Forest River publishes a 16,785-pound GVWR for the Puma Mesa 379MBL against a 14,664-pound unloaded weight, and the 2,121 pounds of cargo carrying capacity that leaves is ranked 5 of 6 on the 6-plan fifth wheel roster. Dry weight plus CCC equals the published GVWR exactly, so the three figures are internally consistent rather than rounded against each other. The dry pin weight is 2,785 pounds before anything is loaded.

The 379MBL measures 42' 7" long, 13' 6" tall and 102" wide, and carries a 75 / 78 / 39-gallon fresh, grey and black tank set with a 13' & 21' awning. Height is the number to check first on a trailer this size — measure garage doors, carports and low branches against the published 13' 6" before the first trip. Against its neighbours on the roster, the shorter 377DS runs 325 pounds lighter dry and the longer 389FLH runs 135 pounds lighter dry.

Equipment for this plan is published as 3 named packages on its factory floorplan record — the “Comfort Package (forced options)” and the “Stainless Steel Residential Style Appliance Package w/18 cu. ft. 12V Refrigerator and Large Range” and the “Voyager Package (forced options)”, listing 15 items and 5 items and 37 items respectively. The first package opens with (2) Residential Style Dinette Chairs, 2 Folding Chairs, Large Kitchen Pantry (Select Models) and Marine Grade Woven Flooring in Slides. Package inclusion on any given unit is not asserted here and Forest River publishes no MSRP for this tier, so confirm delivered equipment and current pricing with a dealer.

Puma Mesa is the fifth wheel tier of Palomino’s Puma family — 6 floorplans filed by the factory under “Fifth Wheels”, sold under the parent Puma line and rostered on the Puma hub’s Puma Mesa section. Per this site’s family policy a factory sub-roster lives under its parent hub rather than taking a hub of its own.

This floorplan carries its water comfortably. A full 75-gallon fresh tank is roughly 29% of the 2,121-pound cargo capacity, leaving the Puma Mesa 379MBL with a usable gear budget even when you tow full.

The published dry pin weight of 2,785 pounds is 19% of this floorplan’s 14,664-pound dry weight. Fifth-wheel pin weight rides in the bed of the truck, so it comes off payload rather than off tow rating — and it rises with the trailer as you load it, not in proportion to what you put over the axles.

Nothing above changes the ceiling. Loaded to its 16,785-pound GVWR the Puma Mesa 379MBL is towing 2,121 pounds more than its 14,664-pound dry figure, and that is the number your vehicle has to be rated for — not the brochure weight.

Tank balance is generous here: 75 gallons of fresh against 78 grey and 39 black, so waste capacity keeps pace with supply and the fresh tank is the constraint that ends a dry stay.

Ranked by GVWR, the Puma Mesa 379MBL sits 30 of 33 in the Puma line: 16,785 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 Mesa 384RKH is 95 pounds lighter at 16,690 lb GVWR; and Puma Grand Mesa 393RL is 1,214 pounds heavier at 17,999 lb GVWR.

Against the Puma Mesa 379MBL: the Montana High Country 373RD is 5 lb lighter and 1 ft shorter; the Nightfall 350N is 5 lb heavier and 2 ft shorter. 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 fifth wheels 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 11 of them for the Puma Mesa 379MBL. 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, sleeps, slide count, axle count, tire specification, refrigerator, air conditioning. 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 (82%) 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.
