01 What makes the 2025 321RSTS different
The Eagle 321RSTS sits in the full-size tier of Jayco's Eagle fifth wheels, above the half-ton Eagle HT and below the luxury North Point and Pinnacle coaches.
Across the 9 model years of the 321RSTS on this site (2018 to 2027), the 2025 record has dry weight 10,770 lbs, between 10,310 lbs (2018) and 11,145 lbs (2026); GVWR 12,900 lbs, between 12,700 lbs (2018) and 13,200 lbs (2026), level with 2023 and 2024; cargo capacity 2,130 lbs, between 1,885 lbs (2020) and 2,390 lbs (2018), level with 2026; dry pin weight 2,155 lbs, between 1895 lbs (2020) and 2,270 lbs (2026); the longest exterior length, 36' 8" (level with 2024).
Against the 2026 321RSTS, the next model year on this site, 9 of the 21 fields both records publish differ: dry weight 10,770 lbs to 11,145 lbs (+375 lb); GVWR 12,900 lbs to 13,200 lbs (+300 lb); dry pin weight 2,155 lbs to 2,270 lbs (+115 lb); exterior length 36' 8" to 36' 7" (-1 in); width with slides out 13' 0" to 14' 1" (+13 in); height with A/C 12' 9" to 12' 8" (-1 in); interior height 8' 7" to 8' 8" (+1 in); tire size ST235/85R16'E' to ST235/80R16'H'; sleeping count up to 6 to up to 4.
Among the 7 Jayco Eagle fifth wheels with a 2025 page on this site, the 321RSTS is the lightest of 7 by dry weight; the lowest of 7 by GVWR; the smallest of 7 by cargo capacity; 2nd shortest of 7 by exterior length. By dry weight, the heaviest is the 355MBQS at 12,830 lbs.

Federal tire recalls naming this size. NHTSA’s recall file names ST235/85R16 in one tire recall: 21T018000 (Sailun Tire Americas, Inc., 2021; make SAILUN; models BLACKHAWK, BLACKLION, IRONHEAD, ROADX, SAILUN). A tire recall covers only the brands, lines and DOT date codes it lists, and this page does not know which brand of tire this trailer was built with, so read the brand and DOT code on your own sidewalls before relying on this list. Only 242 of NHTSA’s 788 tire recalls name a size in their summary, so a size with no match is not a clean record (NHTSA recall file, read 12 Oct 2026).

Towing it
Loaded range: 15–25% of GVWR on the pin, a rule of thumb, not a measurement of this unit. No truck ratings or hitch classes (why; NHTSA, DOT HS 809 433). The range starts at the published dry figure, because loaded is never lighter than dry.
03 What changed for the 2025 model year
Between the 2024 and 2025 321RSTS, 3 of the 20 fields both records publish differ: dry weight, cargo capacity and dry pin weight. The other 17 match, including GVWR.

|---|---|---|---|
| Dry / unit base weight (UVW) | 10,835 lbs | 10,770 lbs | -65 lb |
| Net cargo / payload (CCC) | 2,065 lbs | 2,130 lbs | +65 lb |
| Dry pin weight | 2,065 lbs | 2,155 lbs | +90 lb |

Where these numbers come from
Every figure on this page is read from Jayco's own 2025 model page for this floorplan (how sources are handled).
04 Buying a 2025 321RSTS at 1 model year old
Its age, and the date on its label
A 2025 321RSTS is 1 model year old in 2026. Its build month is on the certification label (49 CFR 567.4(g)(2)), not in the model year.
Tires: size and date code
Jayco lists ST235/85R16'E' as the 2025 factory tire size. Other years on this site list ST235/80R16'H' (2026 and 2027), so a replacement set has to match this year's size. Read the four-digit date code at the end of each tire's identification number, spare included (49 CFR 574.5(b)(3)).
NHTSA record for model year 2025
For model year 2025, NHTSA's files hold 1 recall campaign under the Jayco Eagle name (see Jayco Eagle year by year). Campaigns by component: Equipment (25V140000). They are filed against the line, not this floorplan alone.
05 How it compares — and to its other years
Differs from 2025 on dry weight, cargo capacity and dry pin weight.
Differs from 2025 on 9 of 21 shared fields, dry weight, GVWR and dry pin weight among them.
Model years 2018, 2020, 2021, 2022, 2023, 2024, 2025, 2026 and 2027, side by side.
06 Loading it for a trip
A full 81-gallon fresh tank is about 676 lb of water (water counts as cargo: 49 CFR 571.120 S10.4.2), 32% of the 321RSTS’s 2,130 lb cargo capacity, leaving 1,454 lb (242 lb per rated berth). Your own unit’s figure is on the label inside its entry door (49 CFR 571.120 S10.4.3).

11 NHTSA safety record
NHTSA holds 44 recall campaigns and 114 owner complaints against the Eagle line. They are counted separately: a recall is a confirmed defect with a remedy, a complaint one owner’s unverified account.
What to look at on a used one. Across the 114 complaints filed on this line the most-reported components are tires (23%), structure (18%) and equipment (13%).
Recall coverage here is not complete, and complaints are owners’ unverified reports (how this record is built). Check a specific VIN at NHTSA before you buy. Full tables are on the Eagle line page.
