01 What makes it unique
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.

03 The Eagle floorplan family
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.
| Floorplan | Family | Type | Nominal | Sleeps | Notable |
|---|---|---|---|---|---|
| 265FKDS | Eagle HT | TT | 32 ft | 2 | Front-kitchen couples, dual slide |
| 294CKBS | Eagle HT | TT | 38 ft | 4 | Center-kitchen triple-slide, rear bath |
| 312BHOK | Eagle HT | TT | 39 ft | 8 | Bunkhouse + outside kitchen, triple slide |
| 27MLC | Eagle HT | 5W | 33 ft | 2 | Shortest half-ton 5W, mid-living |
| 29RLC | Eagle HT | 5W | 34 ft | 4 | Rear-living dual-slide half-ton 5W |
| 321RSTS | Eagle | 5W | 37 ft | 4 | Rear-living king triple-slide flagship |
| 355MBQS | Eagle | 5W | 42 ft | 10 | Mid-bunk/den + loft, quad slide |
| 370FBTS | Eagle | 5W | 41 ft | 4 | Front-bath bath-and-a-half full-timer |
The full-size Eagle is offered only as a fifth wheel. Above it sit Jayco's luxury North Point and Pinnacle fifth wheels; below it, the half-ton Eagle HT line in both fifth-wheel and travel-trailer form. Eagle fifth-wheel pin weights are factory dry figures from Jayco's 2026 brochure and climb with cargo — always weigh the loaded coach and confirm your truck's payload, rear-axle and hitch ratings. Additional Eagle floorplans are catalogued on the line hub.
04 What owners & reviewers report
Residential rear living
Triple slides, a king-bed slide and two awnings make it a long-stay coach for two — the flagship Eagle layout.
HELIX dual cooling
Two 15,000-BTU Whisper Quiet units on the HELIX system keep a large fifth wheel comfortable in real heat.
Big tanks, big fridge
An 81-gallon fresh, 87-gallon gray and 16 cu ft residential refrigerator suit extended stays.
Needs a 3/4-ton truck
A 2,055-lb dry pin and 13,200-lb GVWR put it beyond half-ton territory — plan on a 3/4-ton or larger.
05 How it compares
The half-ton rear-living fifth wheel — lighter and lower-pin, if a 3/4-ton truck isn’t available.
A front-bath, bath-and-a-half full-timer layout — more living and bath space for extended use.
Keystone’s iconic rear-living full-size fifth wheel — the direct cross-brand rival.
