Jayco Eagle · 2024–2026370FBTS

The Eagle 370FBTS is the full-timer’s Eagle. Its defining feature is a front bathroom paired with a second rear half-bath — a bath-and-a-half layout that is genuinely rare and a major convenience for couples who live aboard. A king-bed slide anchors the front suite, triple slides open the living space, and dual black tanks (87 gallons combined) reflect the extended-stay mission.

It carries the full Eagle build: Stronghold VBL™ laminated walls, 5-Star Handling and the HELIX dual-15,000-BTU cooling system. A 14,300-pound GVWR on a 12,020-pound dry weight leaves 2,280 pounds of payload, with a 2,105-pound dry pin that calls for a three-quarter-ton or larger truck. An 81-gallon fresh tank, 87-gallon gray, dual black tanks and a 16 cubic-foot residential refrigerator equip it for long off-grid-capable stays.

It sleeps four but is purpose-built for two who live in it, at an MSRP near $83,000. For full-timers or extended travellers who value a second bathroom and full-time-grade tankage over berth count, the front-bath 370FBTS is the long-haul specialist of the Eagle line.

This floorplan has a verified factory record for 3 model years here, 2024 to 2026, and the specification does not hold still. Across those years GVWR ranges from 14,000 lb in 2024 to 14,300 lb in 2025, a spread of 300 lb; dry weight ranges from 11,945 lb in 2024 to 12,195 lb in 2026, a spread of 250 lb; dry pin weight ranges from 2,320 lb in 2024 to 2,375 lb in 2025, a spread of 55 lb. The factory tire size changes over the run (ST235/80R16'H' then ST235/85R16'E'), and the load-range letter in that code is part of the axle rating. Even the published sleeping capacity moves (4 and 6). 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's Eagle is the brand's premium towable family, and it splits three ways. The full-size Eagle is the flagship fifth wheel — Stronghold VBL™ laminated walls, 5-Star Handling, the HELIX dual-15,000-BTU cooling system and a 16 cubic-foot residential refrigerator. The Eagle HT ("half-ton") line is engineered to be towable by a properly equipped half-ton truck, and Jayco offers it as both a fifth wheel and a travel trailer — lighter, 4-Star Handling with Goodyear Endurance tires, and lower pin or tongue weights. The 370FBTS on this page is highlighted; each other profiled plan links to its own page. The full Eagle catalogue runs to dozens of floorplans across all three; the highest-demand layouts are detailed here and the rest are catalogued on the line hub.

Fresh water is the single biggest line in this floorplan’s load plan. A full 81-gallon tank is about 30% of the 2,280-pound cargo capacity — enough that whether you tow with water aboard is a real decision on the 370FBTS rather than a detail.

The published dry pin weight of 2,105 pounds is 18% of this floorplan’s 12,020-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 14,300-pound GVWR the 370FBTS is towing 2,280 pounds more than its 12,020-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 370FBTS sits 34 of 37 in the Eagle line: 14,300 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 370FB is 300 pounds lighter at 14,000 lb GVWR; and Eagle 367TBTS is 600 pounds heavier at 14,900 lb GVWR.

Against the 370FBTS: the Cardinal 35CRIB is 5 lb heavier and 2 ft longer; the Wildcat 35CRIB is 5 lb heavier and 2 ft longer and sleeps 4 more; the Wolf Pack 275PACK15 is 40 lb lighter and 9 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 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 17 of them for the 370FBTS. 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: awning. 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 (97%) 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.
