01 What makes the 2023 320FBOK different
The Eagle 320FBOK 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 2023 320FBOK, 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 11' 1" 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 10,900-pound GVWR on a 8,900-pound dry weight, 2,000 pounds of published cargo capacity, a 1,200-pound dry tongue weight. That dry tongue is 13% 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. The 2023 trailer left the factory on ST225/75R15'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 320FBOK 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 trailer 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 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.

These graphics are generated from the same verified record that builds the table above, and are published under this site’s own licence — nothing here is traced from, or derived from, a manufacturer drawing or photo. Where a figure is not published for this plan, the graphic that would need it is omitted rather than estimated. The full record is in the published dataset.
What it takes to tow this
Built from this floorplan’s verified weights. We publish the trailer side only.
We do not publish tow ratings for specific trucks. A single model can vary by thousands of pounds depending on engine, axle ratio, cab, drivetrain and package — the only authoritative figure is the one on your own door jamb. Loaded tongue percentages are industry convention for travel trailers (10–15% of loaded weight), not a measurement of this unit. Hitch classes are not used here as a rating: SAE J684 covers trailers to 10,000 lb GVWR and does not define Class V, and capacity boundaries differ between manufacturers — read the rating stamped on your hitch. On this plan the convention band’s low end fell below the published dry figure, so the range starts at the published dry weight instead — loaded is never lighter than dry.
03 What changed for the 2023 model year
2023 is the earliest model year of the 320FBOK that this catalogue has a verified factory record for, so there is no earlier year here to compare it against. The years we do publish run 2023 to 2024; each one is linked below.
| Model year | Dry (UVW) | GVWR | Dry tongue | Sleeps | Tire size |
|---|---|---|---|---|---|
| 2023 | 8,900 | 10,900 | 1,200 | 6 | ST225/75R15'E' |
| 2024 | 9,085 | 11,000 | 1,230 | 6 | ST225/75R15'E' |
Every row is that model year's own factory record. The all-years overview for this floorplan, with the family history and the full line, is on the Jayco Eagle 320FBOK parent page.
No published field moved
Jayco's published record for the 2023 320FBOK matches the adjacent year field for field.
Where these numbers come from
Every figure on this page is read from Jayco's own 2023 model page for the 320FBOK — one source, one model year, no blending. This year's figures are read from Jayco's own model-year brochure for the line, named on the page; where a second publisher holds a figure for the same field it is shown beside it rather than replacing it
Fields Jayco does not publish for 2023
For this model year the factory record omits: Propane Unit (lbs) (Optional). Those rows read “Not published” on this page. They are deliberately not filled in from an adjacent model year — a neighbouring year's figure is an inference about this one, not a measurement of it.
04 Buying a 2023 320FBOK 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 trailer the originals (ST225/75R15'E') may still be fitted — read the four-digit date code, not the tread.
Roof and seam sealant is on a service interval
Travel trailers rely on sealant at every roof penetration, along the front cap and around every window and marker light. 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 trailer carries its previous owner's additions, and a travel trailer puts its tongue load on the tow vehicle's hitch and through its rear axle. Weigh the loaded rig at a public scale and check it against the tow vehicle's payload, rear-axle and hitch ratings.

06 Loading it for a trip
Fresh water is the single biggest line in this floorplan’s load plan. A full 81-gallon tank is about 34% of the 2,000-pound cargo capacity — enough that whether you tow with water aboard is a real decision on the 320FBOK rather than a detail.
| Weight budget | Figure | What it means |
|---|---|---|
| Cargo capacity as published (CCC) | 2,000 lb | Everything you add: gear, water, propane, batteries, food, people’s belongings. |
| Fresh tank filled (81 gal × 8.34 lb) | −676 lb | Water is the heaviest thing most owners add, and it is added first. |
| Cargo budget left with a full fresh tank | 1,324 lb | 34% of this plan’s capacity is spent before a single bag is loaded. |
| Per sleeping position, water aboard | 221 lb | A rough share of what is left across the 6 berths this plan sleeps. |
The published dry tongue weight of 1,200 pounds is 13% of the 8,900-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 10,900-pound GVWR the 320FBOK is towing 2,000 pounds more than its 8,900-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 74 grey and 37 black, so waste capacity keeps pace with supply and the fresh tank is the constraint that ends a dry stay.
07 Where this floorplan sits
| Comparable travel trailers | GVWR (lb) | Dry (lb) | Sleeps | Length |
|---|---|---|---|---|
| 320FBOK | 10,900 | 8,900 | 6 | 38 ft 0 in |
| Jay Flight 33RBTS | 10,950 | 8,600 | 14 | 37 ft 10 in |
| Jay Flight SLX 32TSBH | 10,950 | 8,515 | — | 36 ft 2 in |
| Puma Ambush 29TH | 10,995 | 7,813 | — | 37 ft 6 in |
| Reflection 317RSTS | 10,995 | 9,200 | 4 | 35 ft 5 in |
| Wildcat 305MBX | 10,998 | 7,850 | — | 35 ft 6 in |
| Coachmen Catalina 313RLTS | 10,999 | 8,968 | 4 | 36 ft 0 in |
Against the 320FBOK: the Jay Flight 33RBTS is 50 lb heavier and sleeps 8 more; the Jay Flight SLX 32TSBH is 50 lb heavier and 2 ft shorter; the Puma Ambush 29TH is 95 lb heavier. 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.
08 Common questions about the 320FBOK
How much does the 320FBOK weigh?
It leaves the factory at 8,900 pounds dry, and its manufacturer-set loaded ceiling (GVWR) is 10,900 pounds. Real towing weight lands between the two and depends entirely on what you load. Use the GVWR when matching a tow vehicle; the dry figure is only useful for comparing floorplans against each other.
How much can the 320FBOK carry?
Cargo carrying capacity is 2,000 pounds. That is the whole budget: water, propane, batteries, gear and everything you bring. Filling the 81-gallon fresh tank uses about 676 pounds of that.
What is the tongue weight of the 320FBOK?
The published dry tongue weight is 1,200 pounds. It is measured empty; loaded, it runs higher, and it comes out of your tow vehicle’s payload rather than its tow rating.
What size tow vehicle does the 320FBOK need?
Your vehicle needs a tow rating of at least 10,900 pounds — this floorplan’s GVWR — and enough payload left over for the hitch load, passengers and anything in the bed. This site does not publish tow ratings for specific vehicles, because one truck model varies by thousands of pounds across engine, axle ratio, cab and package. The figure that governs is the payload sticker on your own door jamb.
How many people does the 320FBOK sleep?
It is rated to sleep 6. Rated sleeping positions include convertible furniture, so count the beds against how you actually travel rather than against the number.
What are the tank capacities on the 320FBOK?
Fresh 81 gallons, grey 74 gallons, black 37 gallons. Tank sizes set how long the floorplan can sit away from hookups, and the smallest of the three is what ends the stay.
How long is the 320FBOK?
Exterior length is 38' 0". Measure against your site length and your storage before committing — the exterior figure is the one that has to fit, and it includes the tongue or pin box.
Every figure in these answers is read from this page’s verified specification table. Where the manufacturer publishes nothing, the question is not answered rather than estimated.
09 What this page publishes, and what it does not
This catalog tracks 18 specification fields per floorplan. Named sources publish 13 of them for the 320FBOK. 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.
11 NHTSA safety record
This floorplan belongs to the Eagle line, and NHTSA holds 44 recall campaigns and 114 owner complaints against that line. They are separate records and are not added together — a recall is a manufacturer-confirmed defect with a remedy; a complaint is one owner’s account, which NHTSA does not verify.
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%). That is where owners of this family have had trouble, so it is where an inspection is worth the time.
Recall coverage is not complete — our harvest of NHTSA’s recall API ran 1,556 queries, of which 0 failed and 242 returned an explicit zero. A line can still be under-reported where NHTSA files a roster under a parent name, or where a match rests on the wording of the recall rather than its model field. Complaints come from the complete bulk file but are unverified and self-selected: a high count tracks how many units a line sold at least as much as how well it was built. Check a specific VIN at NHTSA before you buy. Full tables are on the Eagle line page.
