Jayco Eagle · 2018306RKDS

The Eagle 306RKDS 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 2018 306RKDS, 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 2018 model year Jayco published a 9,950-pound GVWR on a 7,865-pound dry weight, 2,085 pounds of published cargo capacity, a 1,090-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.

This is the earliest 306RKDS 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 2018 trailer is 8 model years old as of 2026, which puts it squarely in used-buyer territory. Section 05 sets out what to inspect on a travel trailer 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.

2018 is the only model year this catalogue holds a verified factory record for the 306RKDS. That record is published here on its own, and it is not a general specification for the floorplan: Jayco revises published weights, ratings and even tire sizes from one model year to the next, so every figure below is evidence about 2018 and about no other year.

Cargo capacity on the 306RKDS is 2,085 pounds — the entire budget for gear, water, propane, batteries and everything else you put aboard.

The published dry tongue weight of 1,090 pounds is 14% of the 7,865-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 9,950-pound GVWR the 306RKDS is towing 2,085 pounds more than its 7,865-pound dry figure, and that is the number your vehicle has to be rated for — not the brochure weight.

Ranked by GVWR, the 306RKDS sits 7 of 81 in the Eagle line: 9,950 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 24.5KTS matches it exactly at 9,950 lb GVWR; and Eagle 25.5REOK is 45 pounds heavier at 9,995 lb GVWR.

1 other Eagle plan shares this floorplan’s 9,950 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 306RKDS: the Momentum 17MAV is 13 ft shorter; the Seismic 273 is 5 ft shorter; the Puma 31FKRK is 20 lb lighter and 2 ft longer. 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 8 of them for the 306RKDS. 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.
