Jayco Eagle · 2023370FB

The Eagle 370FB 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 2023 370FB, 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' 2" with the slide-outs run out for the 2023 model year, which is the measurement that matters for a site pitch as well as for the road.

For the 2023 model year Jayco published a 14,000-pound GVWR on a 11,905-pound dry weight, 2,095 pounds of published cargo capacity, a 2,365-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. The 2023 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.

This is the earliest 370FB 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 2023 coach is 3 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.

2023 is the only model year this catalogue holds a verified factory record for the 370FB. 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 2023 and about no other year.

Fresh water is the single biggest line in this floorplan’s load plan. A full 81-gallon tank is about 32% of the 2,095-pound cargo capacity — enough that whether you tow with water aboard is a real decision on the 370FB rather than a detail.

The published dry pin weight of 2,365 pounds is 20% of this floorplan’s 11,905-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 14,000-pound GVWR the 370FB is towing 2,095 pounds more than its 11,905-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 87 grey and 87 black, so waste capacity keeps pace with supply and the fresh tank is the constraint that ends a dry stay.

Ranked by GVWR, the 370FB sits 33 of 37 in the Eagle line: 14,000 pounds against a line that runs from 8,400 to 15,200 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 335LSTS is 200 pounds lighter at 13,800 lb GVWR; and Eagle 370FBTS is 300 pounds heavier at 14,300 lb GVWR.

Against the 370FB: the Cougar 364BHL is 1 ft shorter and sleeps 5 more; the Avenue 32RLS is 5 lb lighter and 5 ft shorter and sleeps 1 fewer; the Model Z 2670 is 5 lb lighter and 10 ft shorter and sleeps 2 more. 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 12,830 pounds dry and 28 to 43 feet of exterior length across 37 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 370FB. 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.
