2020 Jayco Eagle HT28.5RSTS

The Eagle HT 28.5RSTS is one of Jayco's Eagle HT fifth wheels, the half-ton tier engineered to be towed by a properly equipped half-ton truck, below the full-size Eagle. This page covers one model year of it — the 2020 28.5RSTS, 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 10,995-pound GVWR on a 8,820-pound dry weight, 2,175 pounds of published cargo capacity, a 1,465-pound dry pin weight. Check the loaded pin against the truck's payload and rear-axle ratings rather than against the tow rating alone.

Against the 2019 build of the same floorplan, 5 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 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.

Jayco changed 5 of the published fields between the 2019 and 2020 28.5RSTS. Every figure in both columns is that model year's own factory record — nothing here is carried across from the other year.

Cargo capacity on the 28.5RSTS is 2,175 pounds — the entire budget for gear, water, propane, batteries and everything else you put aboard.

The published dry pin weight of 1,465 pounds is 17% of this floorplan’s 8,820-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 10,995-pound GVWR the 28.5RSTS is towing 2,175 pounds more than its 8,820-pound dry figure, and that is the number your vehicle has to be rated for — not the brochure weight.

Against the 28.5RSTS: the Reflection 28RL is 2 ft shorter; the Cougar 26RKE is 5 lb heavier and 2 ft shorter; the Roamer Light Duty 304BHS is 395 lb lighter and 1 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 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 28.5RSTS. 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.
