Jayco Eagle · 2019–2025319MLOK

The Eagle 319MLOK sits in the full-size tier of Jayco's Eagle fifth wheels, above the lighter Eagle HT and below the luxury North Point and Pinnacle coaches. This page covers one model year of it — the 2025 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 2025 model year, which is the measurement that matters for a site pitch as well as for the road.

For the 2025 model year Jayco published a 13,300-pound GVWR on a 11,030-pound dry weight, 2,270 pounds of published cargo capacity, a 2,255-pound dry pin weight. Check the loaded pin against the truck's payload and rear-axle ratings rather than against the tow rating alone. The 2025 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 2024 build of the same floorplan, 6 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 2025 coach is close to current as of 2026, but section 05 still applies: check it against its build date rather than its model year. Jayco commonly builds a model year well before the calendar year turns, and the tyre date codes have to be read against the build month, not the badge.

How the 319MLOK differs from the other 51 Eagle fifth wheels. Most distinctive first. Sibling pages may cover other model years than this one (2019–2025). How these ranks are worked out.

• Exterior height, 12 ft 8 in: tallest of 35, level with the 317RLOK, 321RSTS and 367TBTS; next are the 325MKTS, 335LSTS and three others (12 ft 7 in).
• Dry pin weight, 2,255 lb: eighth-heaviest of 52, between the 317RLOK (2,235 lb) and the 370FBTS (2,355 lb).
• Dry pin weight as a share of dry weight, 20.4%: eighth-largest of 52, between the 28RKS and 31QBH (20.3%) and the 27MLC (20.5%).
• Cargo capacity, 2,270 lb: ninth-largest of 52, between the 365UKTS (2,265 lb) and the 335LSTS (2,325 lb).
• Dry weight, 11,030 lb: fourteenth-heaviest of 52, between the 327CKTS (10,920 lb) and the 317RLOK (11,060 lb).
• GVWR, 13,300 lb: shared with the 335RDOK; of 52, 39 lower and eleven higher, nearest the 327CKTS (13,250 lb) and the 365UKTS (13,400 lb).
• Length, 36 ft 9 in: sixteenth-longest of 44, between the 317RLOK and 31QCD (36 ft 6 in) and the 365UKTS (37 ft 2 in).

• Grey tank, 87 gal: shared with the 317RLOK, 321RSTS and twelve others; of 52, 35 smaller and two larger, nearest the 24MLE, 25RUC and nineteen others (82 gal) and the 325BHQS and 347BHOK (95.5 gal).
• Black tank, 50 gal: shared with the 317RLOK, 321RSTS and eight others; of 52, 35 smaller and six larger, nearest the 24MLE, 25RUC and nineteen others (45 gal) and the 336FBOK, 347BHOK and four others (87 gal).

• Sleeping capacity, 4: shared with the 24MLE, 25RUC and fifteen others; of 37, three smaller and sixteen larger, nearest the 26REC, 27MLC and 325MKTS (2) and the 367TBTS and 370FB (5).
• Cargo capacity as a share of GVWR, 17.1%: shared with the 25RUC and 27MLC; of 51, 29 smaller and nineteen larger, nearest the 28RLT, 339FLQS and 355MBQS (17%) and the 31QBH (17.2%).

Next to the 327CKTS (2018 page), the nearest lighter floorplan by dry weight, the 319MLOK is 110 lb heavier by dry weight, has a GVWR 50 lb higher, has 60 lb less cargo capacity, has a dry pin weight 145 lb heavier, is 1 ft 2 in shorter and has a fresh tank 6 gal larger; the two publish the same grey tank, black tank and sleeping capacity.

Next to the 317RLOK (2018–2025 page), the nearest heavier floorplan by dry weight, the 319MLOK is 30 lb lighter by dry weight, has a GVWR 100 lb higher, has 130 lb more cargo capacity, has a dry pin weight 20 lb heavier, is 3 in longer and sleeps two fewer; the two publish the same exterior height, interior height, fresh tank, grey tank and black tank.

This floorplan has a published factory record for 7 model years here, 2019 to 2025. The specification does not hold still: GVWR runs from 12,995 lb (2019) to 13,300 lb (2025); dry weight runs from 10,710 lb (2019) to 11,170 lb (2022); dry pin weight runs from 1,935 lb (2020) to 2,255 lb (2025). The published sleeping capacity changes across the years: 4 - 6 in 2019–2020, 4-6 in 2021, 3-4 in 2022, up to 6 in 2023–2024, up to 4 in 2025. Each year’s complete record is printed separately below, carrying only that year’s own published figures and source. Nothing is copied across from a neighbouring year.

Jayco changed 6 of the published fields between the 2024 and 2025 319MLOK. Every figure in both columns is that model year's own factory record — nothing here is carried across from the other year.

A full 81-gallon fresh tank is about 672 lb of water (water counts as cargo: 49 CFR 571.120 S10.4.2), 30% of the 319MLOK’s 2,270 lb cargo capacity, leaving 1,598 lb (399 lb per rated berth). Across 52 Eagle fifth-wheel floorplans the water share runs 16% to 34%, and 16 give up more than this one. Nearest on that share: Eagle 28BHU at 29% and Eagle 365UKTS at 30%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.120 S10.4.3).
