01 What makes the 2023 319MLOK different
The Eagle 319MLOK 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. This page covers one model year of it — the 2023 319MLOK, exactly as Jayco published it — because the numbers that decide whether your truck can pull this trailer are not the same from one year to the next. Jayco publishes it at 8' 1" wide closed and 13' 1" with the slide-outs run out for the 2023 model year, which is the measurement that matters for a site pitch as well as for the road.
For the 2023 model year Jayco published a 12,995-pound GVWR on a 10,830-pound dry weight, 2,165 pounds of published cargo capacity, a 2,020-pound dry pin weight. A pin weight in that range lands well outside half-ton territory: plan on a three-quarter-ton or larger truck, and check the loaded pin against the truck's payload and rear-axle ratings rather than against the tow rating alone. The 2023 coach left the factory on ST235/85R16'E' tyres; the load range in that code is part of the axle rating and a replacement set has to match it.
Against the 2022 build of the same floorplan, 8 published fields moved. The full comparison is in section 02, and it is drawn from two separate verified factory records rather than from one record and an assumption about the other.
A 2023 coach is 3 model years old as of 2026, which puts it squarely in used-buyer territory. Section 05 sets out what to inspect on a laminated-wall fifth wheel of this age — tyre date codes, roof and seam sealant, slide seals, and the soft-floor and delamination checks that separate a tidy coach from an expensive one.

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 12,995 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 What changed for the 2023 model year
Jayco changed 8 of the published fields between the 2022 and 2023 319MLOK. Every figure in both columns is that model year's own factory record — nothing here is carried across from the other year.
| Field | 2022 | 2023 | Change |
|---|---|---|---|
| Dry weight (UVW) | 11,170 | 10,830 | -340 lb |
| Cargo capacity (CCC) | 1,825 | 2,165 | +340 lb |
| Dry pin weight | 2,023 | 2,020 | -3 lb |
| Exterior length | 36' 7" | 36' 5" | — |
| Black tank | 87 | 50.0 | -37 gal |
| Fresh tank | 87 | 81.0 | -6 gal |
| Grey tank | 87 | 87.0 | — |
| Sleeps | 3-4 | up to 6 | — |
4 fields not compared above. Exterior height; Exterior width, slides out; Furnace output; Tire size. The 2022 figures on this page come from Jayco's own 2022 brochure, which carries no column for them at all; the 2023 figures come from its 2023 model page, which does. That is a difference between two kinds of factory document rather than a change Jayco made to the trailer, so this page does not report it as one and does not count it in the figure above.
| Model year | Dry (UVW) | GVWR | Dry pin | Sleeps | Tire size |
|---|---|---|---|---|---|
| 2020 | 10875 | 12995 | 1935 | Not published | Not published |
| 2021 | Not published | 12,995 | Not published | 6 | Not published |

| 2025 | 11,030 | 13,300 | 2,255 | 4 | ST235/85R16'E' |
Every row is that model year's own factory record. The all-years overview for this floorplan, with the family history and the full line, is on the Jayco Eagle 319MLOK parent page.
Dry pin weight changed for 2023
Dry pin weight was 2,023 for 2022 and is 2,020 for 2023 (-3 lb). Both figures are the manufacturer's own for their year.
Sleeps changed for 2023
Sleeps was 3-4 for 2022 and is up to 6 for 2023. Both figures are the manufacturer's own for their year.
Where these numbers come from
Every figure on this page is read from Jayco's own 2023 model page for the 319MLOK — one source, one model year, no blending. The all-years parent page additionally holds a figure from a second publisher for some fields and publishes both where they disagree, without picking a winner. If the two pages differ on a weight, that is the disclosure working, not an error.
Fields Jayco does not publish for 2023
For this model year the factory record omits: Furnace, Auto-ignition (BTU output). Those rows read “Not published” on this page. They are deliberately not filled in from an adjacent model year — a neighbouring year's figure is an inference about this one, not a measurement of it.
04 Buying a 2023 319MLOK at 3 model years old
Tyres are the first thing to age out
RV tyres are usually replaced on age rather than tread, at roughly five to seven years from the DOT date code on the sidewall. On a 3-year-old coach the originals (ST235/85R16'E') may still be fitted — read the four-digit date code, not the tread.
Roof and seam sealant is on a service interval
Laminated-wall fifth wheels rely on sealant at every roof penetration and along the front cap. Inspection is typically annual and re-sealing every few years; ask for the service records rather than assuming.
Weigh it before you tow it
Every weight on this page is a DRY factory figure for the 2023 model year. A used coach carries its previous owner's additions, and a fifth wheel puts roughly 15-25% of the load through the truck's rear axle. Weigh the loaded rig at a public scale and check it against the truck's payload, rear-axle and hitch ratings.

06 Loading it for a trip
Fresh water is the single biggest line in this floorplan’s load plan. A full 81-gallon tank is about 31% of the 2,165-pound cargo capacity — enough that whether you tow with water aboard is a real decision on the 319MLOK rather than a detail.
| Weight budget | Figure | What it means |
|---|---|---|
| Cargo capacity as published (CCC) | 2,165 lb | Everything you add: gear, water, propane, batteries, food, people’s belongings. |
| Fresh tank filled (81 gal × 8.34 lb) | −676 lb | Water is the heaviest thing most owners add, and it is added first. |
| Cargo budget left with a full fresh tank | 1,489 lb | 31% of this plan’s capacity is spent before a single bag is loaded. |
| Per sleeping position, water aboard | 248 lb | A rough share of what is left across the 6 berths this plan sleeps. |
The published dry pin weight of 2,020 pounds is 19% of this floorplan’s 10,830-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 12,995-pound GVWR the 319MLOK is towing 2,165 pounds more than its 10,830-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.
07 Where this floorplan sits
| Comparable fifth wheels | GVWR (lb) | Dry (lb) | Sleeps | Length |
|---|---|---|---|---|
| 319MLOK | 12,995 | 10,830 | 6 | 36 ft 5 in |
| Cougar 316RLS | 12,900 | 10,792 | 6 | 35 ft 8 in |
| Roamer 32RLTS | 13,200 | 11,050 | — | 36 ft 7 in |
| Wildcat 32LIVE | 13,500 | 10,363 | 4 | 36 ft 5 in |
| Cardinal 32CHILL | 12,188 | 9,688 | — | 35 ft 3 in |
| Open Range 3X 287RLS | 13,900 | 11,670 | — | 34 ft 7 in |
| Avenue 32RLS | 13,995 | 10,500 | 4 | 34 ft 11 in |
Against the 319MLOK: the Cougar 316RLS is 95 lb lighter; the Roamer 32RLTS is 205 lb heavier; the Wildcat 32LIVE is 505 lb heavier and sleeps 2 fewer. 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 13,030 pounds dry and 28 to 43 feet of exterior length across 81 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.
08 Common questions about the 319MLOK
How much does the 319MLOK weigh?
Its published dry weight is 10,830 lb and its GVWR is 12,995 lb, so 2,165 lb separates the empty trailer from its rated maximum. Size the tow vehicle to the 12,995 lb figure, not the dry one.
How much can the 319MLOK carry?
Cargo carrying capacity is 2,165 lb, 17% of the GVWR. Across the 307 fifth wheels on this site that publish both figures, the median share is 19%, so this plan sits 2 points below the median. A full 81-gallon fresh tank is about 676 lb of it (31%), 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 319MLOK?
The published dry pin weight is 2,020 lb, 19% 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 close to 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 319MLOK need?
A tow rating of at least 12,995 lb, this floorplan’s GVWR, plus enough payload for the pin load, passengers and cargo. The dry pin weight alone takes 2,020 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.
How many people does the 319MLOK sleep?
It is rated to sleep 6. Rated positions include convertible furniture.
What are the tank capacities on the 319MLOK?
Fresh 81 gallons, grey 87 gallons, black 50 gallons. The smallest of the three is the black tank, at 50 gallons. Combined waste capacity is 137 gallons.
How long is the 319MLOK?
Exterior length is 36' 5". Check it against campsite and storage length; the exterior figure includes the tongue or pin box.
How does the 2023 319MLOK differ from other model years?
Set against the published 2024 319MLOK record, 4 figures differ: dry weight 10,830 lb in 2023 against 10,940 lb in 2024; cargo capacity 2,165 lb in 2023 against 2,055 lb in 2024; dry hitch weight 2,020 lb in 2023 against 2,145 lb in 2024; exterior length 36 ft 5 in in 2023 against 36 ft 7 in in 2024. 5 other figures both years publish are identical. This floorplan is profiled for 6 model years here (2020 to 2025).
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 13 of the 18 specification fields this catalogue tracks for the 319MLOK (95% complete on the full field set).
Not published for this floorplan: slide count, axle count, awning, refrigerator, air conditioning. Those rows are left blank rather than copied from a sibling floorplan.

11 NHTSA safety record
This floorplan belongs to the Eagle line, and NHTSA holds 44 recall campaigns and 114 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 114 complaints filed on this line the most-reported components are tires (23%), structure (18%) and equipment (13%). 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 Eagle line page.
