Jayco Eagle · 2021–2027321RSTS

The Eagle 321RSTS is the rear-living centerpiece of the full-size Eagle line. Triple slides open a wide rear living and kitchen area, a king-bed slide gives the private front bedroom a real walk-around, and two power awnings stretch the outdoor living space. This is a step up in both size and content from the Eagle HT fifth wheels — a residential coach aimed at couples who spend weeks at a time aboard.

It carries the full Eagle build: Stronghold VBL™ laminated walls, 5-Star Handling, and the industry-exclusive HELIX cooling system with two 15,000-BTU Whisper Quiet air conditioners. A 13,200-pound GVWR on an 11,145-pound dry weight leaves 2,130 pounds of payload, with a 2,055-pound dry pin weight that calls for a three-quarter-ton or larger truck. An 81-gallon fresh tank, 87-gallon gray and a 16 cubic-foot 12-volt residential refrigerator support extended off-grid-capable stays.

It sleeps four in a layout built for comfort and entertaining rather than berth count, at an MSRP near $78,000. For couples who want a full-size, feature-rich fifth wheel without stepping into the luxury North Point or Pinnacle range, the rear-living 321RSTS is the heart of the Eagle line.

This floorplan has a verified factory record for 7 model years here, 2021 to 2027, and the specification does not hold still. Across those years GVWR ranges from 12,700 lb in 2021 to 13,200 lb in 2026, a spread of 500 lb; dry weight ranges from 10,580 lb in 2022 to 11,145 lb in 2026, a spread of 565 lb; dry pin weight ranges from 1,965 lb in 2021 to 2,270 lb in 2026, a spread of 305 lb. The factory tire size changes over the run (ST235/80R16'H' then ST235/85R16'E'), and the load-range letter in that code is part of the axle rating. Even the published sleeping capacity moves (4 and 46 and 6). That is why each model year has its own page below, carrying only its own published figures. Nothing on a year page is copied across from a neighbouring year.

Jayco's Eagle is the brand's premium towable family, and it splits three ways. The full-size Eagle is the flagship fifth wheel — Stronghold VBL™ laminated walls, 5-Star Handling, the HELIX dual-15,000-BTU cooling system and a 16 cubic-foot residential refrigerator. The Eagle HT ("half-ton") line is engineered to be towable by a properly equipped half-ton truck, and Jayco offers it as both a fifth wheel and a travel trailer — lighter, 4-Star Handling with Goodyear Endurance tires, and lower pin or tongue weights. The 321RSTS on this page is highlighted; each other profiled plan links to its own page. The full Eagle catalogue runs to dozens of floorplans across all three; the highest-demand layouts are detailed here and the rest are catalogued on the line hub.

Fresh water is the single biggest line in this floorplan’s load plan. A full 81-gallon tank is about 32% of the 2,130-pound cargo capacity — enough that whether you tow with water aboard is a real decision on the 321RSTS rather than a detail.

The published dry pin weight of 2,055 pounds is 18% of this floorplan’s 11,145-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 13,200-pound GVWR the 321RSTS is towing 2,055 pounds more than its 11,145-pound dry figure, and that is the number your vehicle has to be rated for — not the brochure weight.

Tank balance is generous here: 81 gallons of fresh against 87 grey and 50 black, so waste capacity keeps pace with supply and the fresh tank is the constraint that ends a dry stay.

Ranked by GVWR, the 321RSTS sits 28 of 37 in the Eagle line: 13,200 pounds against a line that runs from 8,400 to 15,200 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: Eagle 317RLOK matches it exactly at 13,200 lb GVWR; and Eagle 319MLOK is 100 pounds heavier at 13,300 lb GVWR.

1 other Eagle plan shares this floorplan’s 13,200 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 321RSTS: the Cougar 316RLS is 300 lb lighter and sleeps 2 more; the Wildcat 32LIVE is 300 lb heavier; the Sabre 32GKS is 308 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 Eagle floorplans profiled here run 6,560 to 12,830 pounds dry and 28 to 43 feet of exterior length across 37 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 Eagle line hub.

This catalog tracks 18 specification fields per floorplan. Named sources publish 17 of them for the 321RSTS. 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: awning. 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 (97%) 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.

How every figure here was sourced and checked is set out on the methodology page.
