2020 Jayco Eagle319MLOK

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 2020 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.

For the 2020 model year Jayco published a 12995-pound GVWR on a 10875-pound dry weight, 2,120 pounds of published cargo capacity, a 1935-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.

This is the earliest 319MLOK model year with a verified factory record in this catalogue. Later years are linked at the foot of the page, each with its own published figures.

A 2020 coach is 6 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.

2020 is the earliest model year of the 319MLOK that this catalogue has a verified factory record for, so there is no earlier year here to compare it against. The years we do publish run 2020 to 2025; each one is linked below.

Cargo capacity on the 319MLOK is 2,120 pounds — the entire budget for gear, water, propane, batteries and everything else you put aboard.

The published dry pin weight of 1,935 pounds is 18% of this floorplan’s 10,875-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 2,120 pounds more than its 10,875-pound dry figure, and that is the number your vehicle has to be rated for — not the brochure weight.

Against the 319MLOK: the Cougar 316RLS is 95 lb lighter; the Roamer 32RLTS is 205 lb heavier; the Wildcat 32LIVE is 505 lb heavier. 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.

This catalog tracks 18 specification fields per floorplan. Named sources publish 8 of them for the 319MLOK. 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: exterior height, fresh tank, grey tank, sleeps, slide count, axle count, tire specification, awning, refrigerator, air conditioning. 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 (43%) 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.
