Jayco Pinnacle · 2026–202739FLOK

The 39FLOK is the top of the Pinnacle line: a front ‘FL’ living area raised over the hitch as a great room, a rear bathroom, an outdoor kitchen and five slide-outs — the most in the line — sleeping six, the only Pinnacle that does. The raised front living room, the mid galley and the rear bath open into a wide main level, with the outside kitchen moving cooking into the open air. The equipment is the full Pinnacle package — a GE 21-cubic-foot 12-volt residential refrigerator, a GE Profile 24-inch range and 30-inch convection microwave, solid-surface counters and a fireplace — on the 102-inch wide-body chassis with Dexter axles, six-point hydraulic auto-leveling and a MORryde LRE-4000 suspension.

Jayco publishes an 18,800-pound GVWR against the 15,870-pound dry weight — the heaviest in the line — leaving a 2,930-pound cargo capacity and a 3,095-pound dry pin. Two 15,000-BTU Whisper Quiet air conditioners, a 40,000-BTU furnace, an on-demand tankless water heater, the Overlander II solar package and 75/82/74-gallon fresh/grey/black tanks are standard. At a starting MSRP around $145,000 it is the priciest Pinnacle, with street pricing below placard. For buyers who want a raised front great room, an outdoor kitchen and six-berth capacity in a luxury full-profile coach, towed with a one-ton truck, the 39FLOK is the flagship.

This floorplan has a verified factory record for 2 model years here, 2026 to 2027, and the specification does not hold still. Across those years dry weight ranges from 15,870 lb in 2026 to 15,920 lb in 2027, a spread of 50 lb; dry pin weight ranges from 3,085 lb in 2027 to 3,095 lb in 2026, a spread of 10 lb. The factory tire size changes over the run (215/75R17.5'H' then ST215/75R17.5'H'), and the load-range letter in that code is part of the axle rating. 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.

Pinnacle is Jayco's flagship luxury full-profile fifth wheel — a cross-shop against Grand Design's Solitude, Keystone's Montana High Country, Alliance's Paradigm and Brinkley. The 2026 line runs to six floorplans, all profiled in full and linked below. The 39FLOK on this page is highlighted.

This floorplan carries its water comfortably. A full 75-gallon fresh tank is roughly 21% of the 2,930-pound cargo capacity, leaving the 39FLOK with a usable gear budget even when you tow full.

The published dry pin weight of 3,095 pounds is 20% of this floorplan’s 15,870-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 2,930 pounds more than its 15,870-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.

Of the 10 Pinnacle floorplans profiled here, the 39FLOK carries the highest GVWR at 18,800 pounds. It is the top of the line by weight, which makes tow-vehicle capability the first thing to settle rather than the last.

Either side of it in the same line: Pinnacle 38SSWS is 100 pounds lighter at 18,700 lb GVWR.

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 2 ft shorter 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.

This catalog tracks 18 specification fields per floorplan. Named sources publish 17 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: interior height, tire size (a tire description is published, a size is not). 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.
