01 What makes it unique
The 38FBRK combines two features buyers ask for: a residential ‘RK’ kitchen across the rear wall and a private ‘FB’ master bath up front, with a half-bath added amidships for a bath-and-a-half. The raised front holds a king bedroom with its own bath, the living area sits in the middle and the full galley runs across the back. It opens on three slide-outs and sleeps four. The equipment is the standard 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 18,200-pound GVWR against the 15,448-pound dry weight, leaving a 2,752-pound cargo capacity and a 2,940-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 75/87/87-gallon fresh/grey/black tanks — with generous grey and black capacity — are standard. At a starting MSRP around $133,000, with street pricing below placard, the 38FBRK is the Pinnacle for buyers who want a residential rear kitchen, a private front bath and a bath-and-a-half in a luxury full-profile coach, towed with a one-ton truck.

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
Rear kitchen + front bath + half bath
A residential rear galley, a private front master bath off the king suite and a mid-coach half bath — a bath-and-a-half layout.
Generous holding tanks
87-gallon grey and 87-gallon black tanks support long stays for a couples’ coach.
Lower cargo headroom
Its 2,752-pound CCC is the smallest in the profiled group — watch loaded weight if you carry a lot of gear and water.
Wants a one-ton truck
At 43 feet 10 inches on an 18,200-pound GVWR, confirm a properly rated one-ton truck’s payload and rear-axle rating.
05 How it compares
Grand Design’s luxury rear-kitchen Solitude — the direct residential-galley cross-shop.
The independent maker’s rear-kitchen luxury coach — a comparable long full-profile cross-shop.
The front-living 39FLOK — five slides, an outdoor kitchen and the line’s highest berth count.
