01 What makes it unique
Forest River publishes a 16,480-pound GVWR for the Puma Mesa 377DS against a 14,339-pound unloaded weight, and the 2,141 pounds of cargo carrying capacity that leaves is ranked 4 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 2,480 pounds before anything is loaded.
The 377DS measures 42' 7" long, 13' 6" tall and 102" wide, and carries a 75 / 117 / 78-gallon fresh, grey and black tank set with a 11'6" & 15' 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 383RLH runs 730 pounds lighter dry and the longer 379MBL runs 325 pounds heavier 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.

What it takes to tow this
Built from this floorplan’s verified weights. We publish the trailer side only.
Truck tow ratings are not listed: one model varies by thousands of pounds across engine, axle ratio, cab and package. The loaded range is the 15–25% pin-weight convention for fifth wheels, applied to this plan’s 16,480 lb GVWR, not a measurement of this unit. Hitch class is not used as a rating (SAE J684 covers trailers to 10,000 lb GVWR); 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 Mesa roster
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.
| Floorplan | Nominal | Cargo (CCC) | Published GVWR | Page |
|---|---|---|---|---|
| 383RLH | 41 ft | 3,026 lbs | 16,635 lbs GVWR | profiled |
| 377DS | 42 ft | 2,141 lbs | 16,480 lbs GVWR | profiled |

04 Notes on this floorplan
The published figures tie out exactly
Dry 14,339 plus CCC 2,141 equals the published GVWR of 16,480 — no rounding gap.
A 2,480-pound dry pin weight
Pin weight lands on the truck bed, not a hitch ball — check the truck's payload rating, not just its tow rating, and confirm the bed and hitch are rated for it loaded.
13' 6" of height
Measure garage doors, carports, awnings and low branches against this figure before the first trip.
Sleeps, slides and axles are not published
Forest River publishes no sleeping capacity, slide count, entry count, axle count or rating, or tire size for this tier — confirm the layout and running gear on the unit itself.
Weigh the loaded trailer
Dry weight is a factory estimate for a base unit; options, water and cargo all add to it. Weigh loaded and confirm against your tow vehicle's ratings and the unit's weight sticker before purchase.
05 How it compares
730 pounds lighter dry on a 2,635-pound pin weight.
325 pounds heavier dry, 2,121 lbs of CCC.
Forest River’s own fifth-wheel roster in the class above.
06 Loading it for a trip
This floorplan carries its water comfortably. A full 75-gallon fresh tank is roughly 29% of the 2,141-pound cargo capacity, leaving the Puma Mesa 377DS with a usable gear budget even when you tow full.
| Weight budget | Figure | What it means |
|---|---|---|
| Cargo capacity as published (CCC) | 2,141 lb | Everything you add: gear, water, propane, batteries, food, people’s belongings. |
| Fresh tank filled (75 gal × 8.34 lb) | −626 lb | Water is the heaviest thing most owners add, and it is added first. |
| Cargo budget left with a full fresh tank | 1,515 lb | 29% of this plan’s capacity is spent before a single bag is loaded. |
The published dry pin weight of 2,480 pounds is 17% of this floorplan’s 14,339-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 16,480-pound GVWR the Puma Mesa 377DS is towing 2,141 pounds more than its 14,339-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 117 grey and 78 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 Puma Mesa 377DS sits 25 of 33 in the Puma line: 16,480 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 Vista 421LFT is 1,181 pounds lighter at 15,299 lb GVWR; and Puma Mesa 389FLH is 75 pounds heavier at 16,555 lb GVWR.
| Comparable fifth wheels | GVWR (lb) | Dry (lb) | Sleeps | Length |
|---|---|---|---|---|
| Puma Mesa 377DS | 16,480 | 14,339 | — | 42 ft 7 in |
| Columbus 377DS | 16,480 | 14,339 | — | 42 ft 7 in |
| Montana 3531RE | 16,480 | 13,345 | 4 | 38 ft 7 in |
| Seismic 403 | 16,500 | 13,260 | 7 | 41 ft 6 in |
| Cedar Creek 360RL | 16,525 | 13,134 | — | 40 ft 7 in |
| Sandstorm 3300 | 16,555 | 10,879 | — | 36 ft 10 in |
| Momentum 320G | 16,400 | 13,100 | 6 | 36 ft 3 in |
Against the Puma Mesa 377DS: the Montana 3531RE is 4 ft shorter; the Seismic 403 is 20 lb heavier and 1 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.
08 Common questions about the Puma Mesa 377DS
How much does the Puma Mesa 377DS weigh?
Its published dry weight is 14,339 lb and its GVWR is 16,480 lb, so 2,141 lb separates the empty trailer from its rated maximum. By GVWR it is the 9th-heaviest of the 33 Puma floorplans profiled here that publish a GVWR (8,553 lb to 18,575 lb). Size the tow vehicle to the 16,480 lb figure, not the dry one.
How much can the Puma Mesa 377DS carry?
Cargo carrying capacity is 2,141 lb, 13% of the GVWR. Across the 307 fifth wheels on this site that publish both figures, the median share is 19%, so this plan sits 6 points below the median. A full 75-gallon fresh tank is about 626 lb of it (29%), because federal rule counts on-board water as cargo (49 CFR 571.120 S10.4.2). The yellow cargo-capacity label inside your own trailer’s entry door (49 CFR 571.120 S10.4.3) states the figure for that unit as delivered, options included, and it is the one that binds.
What is the pin weight of the Puma Mesa 377DS?
The published dry pin weight is 2,480 lb, 17% of the dry weight. Across the 386 fifth wheels on this site that publish both figures, the median dry pin share is 19%, so this plan sits 2 points below the median. Loaded, it changes with where the cargo sits, and it is carried by the tow vehicle’s payload, not its tow rating.
What size tow vehicle does the Puma Mesa 377DS need?
A tow rating of at least 16,480 lb, this floorplan’s GVWR, plus enough payload for the pin load, passengers and cargo. The dry pin weight alone takes 2,480 lb of that payload before anything is loaded. Payload is printed on the tire and loading placard on the tow vehicle’s driver-side door pillar (49 CFR 571.110 S4.3); this site lists no truck ratings because they vary by build.
What are the tank capacities on the Puma Mesa 377DS?
Fresh 75 gallons, grey 117 gallons, black 78 gallons. The smallest of the three is the fresh tank, at 75 gallons. Combined waste capacity is 195 gallons.
How long is the Puma Mesa 377DS?
Exterior length is 42' 7". That makes it the 13th-longest of the 33 Puma floorplans profiled here that publish an exterior length (29 ft 9 in to 43 ft 1 in). Check it against campsite and storage length; the exterior figure 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
Named sources publish 11 of the 18 specification fields this catalogue tracks for the Puma Mesa 377DS (82% complete on the full field set).
Not published for this floorplan: interior height, sleeps, slide count, axle count, tire specification, refrigerator, air conditioning. Those rows are left blank rather than copied from a sibling floorplan.
Values marked with an asterisk are arithmetic on published figures or come from a single source; the flag travels into the downloadable spec sheet.

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.
