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.

A full 75-gallon fresh tank is about 626 lb of water (water counts as cargo: 49 CFR 571.120 S10.4.2), 21% of the 39FLOK’s 2,930 lb cargo capacity, leaving 2,304 lb (384 lb per rated berth). Across 11 Pinnacle floorplans the water share runs 19% to 26%, and 3 give up more than this one. Nearest on that share: Pinnacle 32RLTS at 21% and Pinnacle 36SSWS at 21%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.120 S10.4.3).

Closest sibling: the Pinnacle 38FLGS, nearest on the published figures. It differs on 6 of the 9 fields both publish (this plan first): length 44 ft 6 in vs 44 ft 5 in; dry weight 15,870 lb vs 15,455 lb; GVWR 18,800 lb vs 18,500 lb; cargo capacity 2,930 lb vs 3,045 lb; dry hitch weight 3,095 lb vs 2,900 lb; grey tank 82 gal vs 82 gal. They match on sleeps, fresh tank and black tank.

Either side of it by GVWR: Pinnacle 38SSWS is 100 lb lighter (18,700 lb GVWR).

All 11 Pinnacle floorplans: Pinnacle line hub.

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.
