01 What makes it unique
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.

Pinnacle is Jayco's flagship luxury full-profile fifth wheel. The 2026 line runs to six floorplans, all profiled here in full. Every Pinnacle rides a 102-inch wide-body chassis built on a 12-inch steel I-beam with an 8/10-inch monster-beam drop frame, on Dexter axles with ABS, 17.5-inch 16-ply H-rated tires with SpartanLync TPMS, a MORryde LRE-4000 rubberized suspension and a MORryde rubber pin box, with six-point hydraulic auto-leveling, Stronghold VBL laminated fiberglass walls, a Magnum Truss XL6 roof, Climate Shield zero-degree insulation and an enclosed heated underbelly. The residential package is standard: a GE 21-cubic-foot 12-volt refrigerator, a GE Profile 24-inch range and 30-inch convection microwave, solid-surface counters, 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 JAYCOMMAND smart controls. Dry weight, GVWR, CCC and pin are the factory figures; dry weight plus CCC equals GVWR exactly on every plan except the 38SSWS. Real loaded pin weights run higher — always weigh the loaded coach and confirm against your truck's payload and rear-axle ratings.
04 What owners & reviewers report
Front living + outdoor kitchen
A raised front great room over the hitch, a rear bath and an outside kitchen — a distinct alternative to the rear-living plans.
Five slides, sleeps six
The only six-berth Pinnacle and the only five-slide plan — the widest, most family-capable layout in the line.
Longest, heaviest Pinnacle
At 44½ feet and a 15,870-pound dry weight it is the biggest coach in the range, with a 3,095-pound pin.
Wants a one-ton truck
At an 18,800-pound GVWR and a 3,095-pound pin, confirm a properly rated one-ton truck’s payload and rear-axle rating.
05 How it compares
Grand Design’s luxury Solitude — a full-profile luxury-5W cross-shop at the top of the class.
The independent maker’s front-living luxury coach — a comparable raised-front-great-room fifth wheel.
The rear-living 38SSWS — lighter, three slides and a rear living area instead of a front great room.
