01 What makes the 2023 370FB different
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.
Specifications by model year
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.
| Model year | Dry (UVW) | GVWR | Cargo (CCC) | Dry pin | Sleeps | Tire size |
|---|---|---|---|---|---|---|
| 2023 | 11,905 | 14,000 | 2,095 | 2,365 | 5 | ST235/85R16'E' |
The row above is the 2023 model year’s own record from Jayco’s model page for that year. When a second model year is sourced for this floorplan, it joins the table above on this same page and at this same address — nothing moves and no link breaks. The figures in the tow-critical placard at the top of this page are that same 2023 record. On the weights, overall length and tire size, that record and Jayco’s own 2023 model page agree on every field both of them publish. Exterior height is not compared: Jayco publishes a bare height, a with-A/C height and a with-2nd-A/C height, and the single height row carried here cannot be matched to one of them, so no claim is made either way.

Federal tire recalls naming this size. NHTSA’s recall file names ST235/85R16 in one tire recall: 21T018000 (Sailun Tire Americas, Inc., 2021; make SAILUN; models BLACKHAWK, BLACKLION, IRONHEAD, ROADX, SAILUN). A tire recall covers only the brands, lines and DOT date codes it lists, and this page does not know which brand of tire this trailer was built with, so read the brand and DOT code on your own sidewalls before relying on this list. Only 242 of NHTSA’s 788 tire recalls name a size in their summary, so a size with no match is not a clean record (NHTSA recall file, read 12 Oct 2026).

Towing it
Loaded range: 15–25% of GVWR on the pin, a rule of thumb, not a measurement of this unit. No truck ratings or hitch classes (why; NHTSA, DOT HS 809 433). The range starts at the published dry figure, because loaded is never lighter than dry.
04 Buying a 2023 370FB at 3 model years old
Tyres are the first thing to age out
RV tyres are usually replaced on age rather than tread, at roughly five to seven years from the DOT date code on the sidewall. On a 3-year-old coach the originals (ST235/85R16'E') may still be fitted — read the four-digit date code, not the tread.
Roof and seam sealant is on a service interval
Laminated-wall fifth wheels rely on sealant at every roof penetration and along the front cap. Inspection is typically annual and re-sealing every few years; ask for the service records rather than assuming.
Weigh it before you tow it
Every weight on this page is a DRY factory figure for the 2023 model year. A used coach carries its previous owner's additions, and a fifth wheel puts roughly 15-25% of the load through the truck's rear axle. Weigh the loaded rig at a public scale and check it against the truck's payload, rear-axle and hitch ratings.
05 How it compares
Every Eagle floorplan this catalogue holds a verified factory record for, with its own published weights.
06 Loading it for a trip
A full 81-gallon fresh tank is about 676 lb of water (water counts as cargo: 49 CFR 571.120 S10.4.2), 32% of the 370FB’s 2,095 lb cargo capacity, leaving 1,419 lb (284 lb per rated berth). Across 32 Eagle fifth-wheel floorplans the water share runs 21% to 33%, and 1 gives up more than this one. Nearest on that share: Eagle 317RLOK at 32% and Eagle 31MB at 33%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.120 S10.4.3).
07 Where this floorplan sits
Closest sibling: the Eagle 336FBOK, nearest on the published figures. It differs on 5 of the 6 fields both publish (this plan first): length 40 ft 3 in vs 39 ft 8 in; dry weight 11,905 lb vs 11,682 lb; GVWR 14,000 lb vs 13,750 lb; cargo capacity 2,095 lb vs 2,068 lb; dry hitch weight 2,365 lb vs 2,216 lb. They match on black tank.

11 NHTSA safety record
NHTSA holds 44 recall campaigns and 114 owner complaints against the Eagle line. They are counted separately: a recall is a confirmed defect with a remedy, a complaint one owner’s unverified account.
What to look at on a used one. Across the 114 complaints filed on this line the most-reported components are tires (23%), structure (18%) and equipment (13%).
Recall coverage here is not complete, and complaints are owners’ unverified reports (how this record is built). Check a specific VIN at NHTSA before you buy. Full tables are on the Eagle line page.
