01 What makes the 2027 39FLOK different
The Pinnacle 39FLOK is one of Jayco's Pinnacle coaches, the flagship of the Jayco towable lineup, above the North Point and Eagle fifth wheels. This page covers one model year of it — the 2027 39FLOK, 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' 6" wide closed and 14' 6" with the slide-outs run out for the 2027 model year, which is the measurement that matters for a site pitch as well as for the road.
For the 2027 model year Jayco published a 18,800-pound GVWR on a 15,920-pound dry weight, 2,880 pounds of published cargo capacity, a 3,085-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 2027 coach left the factory on ST215/75R17.5'H' tyres; the load range in that code is part of the axle rating and a replacement set has to match it.
Against the 2026 build of the same floorplan, 8 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 2027 coach is close to current as of 2026, but section 05 still applies: check it against its build date rather than its model year. Jayco commonly builds a model year well before the calendar year turns, and the tyre date codes have to be read against the build month, not the badge.

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We do not publish tow ratings for specific trucks.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 pin percentages are industry convention for fifth wheels (15–25% 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 2027 model year
Jayco changed 8 of the published fields between the 2026 and 2027 39FLOK. Every figure in both columns is that model year's own factory record — nothing here is carried across from the other year.
| Field | 2026 | 2027 | Change |
|---|---|---|---|
| Dry weight (UVW) | 15,870 | 15,920 | +50 lb |
| Cargo capacity (CCC) | 2,930 | 2,880 | -50 lb |
| Dry pin weight | 3,095 | 3,085 | -10 lb |
| Exterior length | 44' 6" | Not published | — |
| Exterior height | Not published | 12' 6" | — |
| Exterior width, slides out | 13' 5" | 14' 6" | — |
| Interior height | 6' 7" | 8' 6" | — |
| Tire size | 215/75R17.5'H' | ST215/75R17.5'H' | — |
| Model year | Dry (UVW) | GVWR | Dry pin | Sleeps | Tire size |
|---|---|---|---|---|---|
| 2026 | 15,870 | 18,800 | 3,095 | 6 | 215/75R17.5'H' |
| 2027 | 15,920 | 18,800 | 3,085 | 6 | ST215/75R17.5'H' |
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 Pinnacle 39FLOK parent page.
Dry pin weight changed for 2027
Dry pin weight was 3,095 for 2026 and is 3,085 for 2027 (-10 lb). Both figures are the manufacturer's own for their year.
Tire size changed for 2027
Tire size was 215/75R17.5'H' for 2026 and is ST215/75R17.5'H' for 2027. Both figures are the manufacturer's own for their year.
Where these numbers come from
Every figure on this page is read from Jayco's own 2027 model page for the 39FLOK — one source, one model year, no blending. The all-years parent page sets this year beside every other model year we hold, and where the record this catalogue originally profiled disagrees with Jayco's own model page, both figures are published there and neither is adjusted.
Fields Jayco does not publish for 2027
For this model year the factory record omits: Exterior Length (overall), Propane Unit (lbs) (Optional), Furnace BTU, Furnace, Auto-ignition (BTU output). 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 2027 39FLOK today
Still in warranty
A current-model-year coach is normally inside Jayco's structural and component warranties. Get the delivery PDI paperwork and confirm the warranty start date is the date of sale, not the date of build.
Check the build date, not the model year
Model-year 2027 units can be built well before the calendar year turns. The federal certification label inside the entry door carries the real month of manufacture, and it is what the tyre date codes should be read against.
Weigh it before you tow it
Every weight on this page is a DRY factory figure for the 2027 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.

06 Loading it for a trip
This floorplan carries its water comfortably. A full 75-gallon fresh tank is roughly 22% of the 2,880-pound cargo capacity, leaving the 39FLOK with a usable gear budget even when you tow full.
| Weight budget | Figure | What it means |
|---|---|---|
| Cargo capacity as published (CCC) | 2,880 lb | Everything you add: gear, water, propane, batteries, food, people’s belongings. |
| Fresh tank filled (75 gal × 8.34 lb) | −626 lb | Water is the heaviest thing most owners add, and it is added first. |
| Cargo budget left with a full fresh tank | 2,254 lb | 22% of this plan’s capacity is spent before a single bag is loaded. |
| Per sleeping position, water aboard | 376 lb | A rough share of what is left across the 6 berths this plan sleeps. |
The published dry pin weight of 3,085 pounds is 19% of this floorplan’s 15,920-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 18,800-pound GVWR the 39FLOK is towing 2,880 pounds more than its 15,920-pound dry figure, and that is the number your vehicle has to be rated for — not the brochure weight.
Tank balance is generous here: 75 gallons of fresh against 82 grey and 74 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 fifth wheels | GVWR (lb) | Dry (lb) | Sleeps | Length |
|---|---|---|---|---|
| 39FLOK | 18,800 | 15,920 | 6 | — |
| North Point 395DSDB | 18,800 | 15,925 | 8 | 44 ft 9 in |
| Bighorn 40DB | 18,850 | 16,110 | 8 | 43 ft 10 in |
| Riverstone 39RKFB | 18,975 | 16,511 | 4 | 42 ft 1 in |
| Seismic 3512 | 18,995 | 14,285 | 7 | 41 ft 7 in |
| Influence 3804DS | 19,000 | 14,603 | 6 | 42 ft 6 in |
| Momentum 344M | 19,000 | 15,910 | 6 | 39 ft 11 in |
Against the 39FLOK: the North Point 395DSDB sleeps 2 more; the Bighorn 40DB is 50 lb heavier and sleeps 2 more; the Riverstone 39RKFB is 175 lb heavier and sleeps 2 fewer. 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 Pinnacle floorplans profiled here run 13,545 to 15,870 pounds dry and 36 to 44 feet of exterior length across 10 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 Pinnacle line hub.
08 Common questions about the 39FLOK
How much does the 39FLOK weigh?
It leaves the factory at 15,920 pounds dry, and its manufacturer-set loaded ceiling (GVWR) is 18,800 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 39FLOK carry?
Cargo carrying capacity is 2,880 pounds. That is the whole budget: water, propane, batteries, gear and everything you bring. Filling the 75-gallon fresh tank uses about 626 pounds of that.
What is the pin weight of the 39FLOK?
The published dry pin weight is 3,085 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 39FLOK need?
Your vehicle needs a tow rating of at least 18,800 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 39FLOK 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 39FLOK?
Fresh 75 gallons, grey 82 gallons, black 74 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 39FLOK?
Exterior length is Not published. 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 12 of them for the 39FLOK. 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 length, 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 (81%) 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 Pinnacle line, and NHTSA holds 18 recall campaigns and 31 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 31 complaints filed on this line the most-reported components are suspension (48%), structure (23%) and wheels (10%). 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 Pinnacle line page.
