Jayco Eagle · 2023–2024320FBOK

The Eagle 320FBOK sits in Jayco's Eagle travel-trailer range, the towable-behind-a-half-ton side of the Eagle name, below the Eagle fifth wheels and above the lighter Jay Feather. This page covers one model year of it — the 2024 320FBOK, 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 11' 1" with the slide-outs run out for the 2024 model year, which is the measurement that matters for a site pitch as well as for the road.

For the 2024 model year Jayco published a 11,000-pound GVWR on a 9,085-pound dry weight, 1,915 pounds of published cargo capacity, a 1,230-pound dry tongue weight. That dry tongue is 14% of the dry weight, inside the 10–15% band conventionally quoted for a bumper-pull trailer. Tongue weight is not fixed — it moves with how the trailer is loaded, and weight added ahead of the axles raises it. A tongue load in that range wants a weight-distribution hitch, and the tow vehicle's tongue-weight limit is a separate number from its trailer-weight limit — check the loaded tongue against the hitch receiver's rating and the vehicle's payload, not against the tow rating alone. The 2024 trailer left the factory on ST225/75R15'E' tyres; the load range in that code is part of the axle rating and a replacement set has to match it.

Against the 2023 build of the same floorplan, 4 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 2024 trailer 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.

This floorplan has a verified factory record for 2 model years here, 2023 to 2024, and the specification does not hold still. Across those years GVWR ranges from 10,900 lb in 2023 to 11,000 lb in 2024, a spread of 100 lb; dry weight ranges from 8,900 lb in 2023 to 9,085 lb in 2024, a spread of 185 lb; dry tongue weight ranges from 1,200 lb in 2023 to 1,230 lb in 2024, a spread of 30 lb. That is why each model year has its own page below, carrying only its own published figures. Nothing on a year page is copied across from a neighbouring year.

Jayco changed 4 of the published fields between the 2023 and 2024 320FBOK. Every figure in both columns is that model year's own factory record — nothing here is carried across from the other year.

Fresh water is the single biggest line in this floorplan’s load plan. A full 81-gallon tank is about 35% of the 1,915-pound cargo capacity — enough that whether you tow with water aboard is a real decision on the 320FBOK rather than a detail.

The published dry tongue weight of 1,230 pounds is 14% of the 9,085-pound dry weight, which sits inside the 10–15% band usually quoted for stable towing. It is still a dry figure: loading the front pass-through and the fresh tank both push it up.

Nothing above changes the ceiling. Loaded to its 11,000-pound GVWR the 320FBOK is towing 1,915 pounds more than its 9,085-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 74 grey and 37 black, so waste capacity keeps pace with supply and the fresh tank is the constraint that ends a dry stay.

Ranked by GVWR, the 320FBOK sits 37 of 81 in the Eagle line: 11,000 pounds against a line that runs from 8,400 to 15,400 pounds. That position is the useful thing to know, because the plans immediately either side of it are the real alternatives.

Either side of it in the same line: Eagle 30.5MLOK matches it exactly at 11,000 lb GVWR; and Eagle 29RLC is 200 pounds heavier at 11,200 lb GVWR.

3 other Eagle plans share this floorplan’s 11,000 lb GVWR, so the ranking above separates plans that tow to the same ceiling. On a shared chassis the figure that actually differs between them is cargo capacity and where the weight sits, not the rating.

Against the 320FBOK: the Momentum 21G is 11 ft shorter; the Outback 340BH sleeps 4 more; the Pause 22.4 is 11 ft shorter. 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 travel trailers 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 13 of them for the 320FBOK. 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: slide count, axle count, 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 (95%) 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.
