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.
Specifications by model year
This floorplan has a verified factory record for 4 model years here, 2024 to 2027, and the specification does not hold still. Across those years GVWR ranges from 18,000 lb in 2024 to 18,200 lb in 2026, a spread of 200 lb; dry weight ranges from 14,995 lb in 2024 to 15,475 lb in 2027, a spread of 480 lb; dry pin weight ranges from 2,940 lb in 2024 to 3,035 lb in 2027, a spread of 95 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.
| Model year | Dry (UVW) | GVWR | Cargo (CCC) | Dry pin | Sleeps | Tire size |
|---|---|---|---|---|---|---|
| 2024 | 14,995 | 18,000 | 3,005 | 2,940 | 4 | 215/75R17.5'H' |
| 2025 | 15,330 | 18,000 | 2,870 | 2,975 | 4 | 215/75R17.5'H' |
| 2026 | 15,448 | 18,200 | 2,752 | 2,940 | 4 | 215/75R17.5'H' |
| 2027 | 15,475 | 18,200 | 2,752 | 3,035 | 4 | ST215/75R17.5'H' |
Every row is that model year’s own record from Jayco’s model page for that year. The figures in the tow-critical placard at the top of this page are the 2026 record from the source this catalogue originally profiled. On the weights, overall length and tire size, that record and Jayco’s own 2026 model page agree on every field both of them publish. Exterior height is not compared: Jayco publishes a bare height, a with-A/C height and a with-2nd-A/C height, and the single height row carried here cannot be matched to one of them, so no claim is made either way.

Towing it
Loaded range: 15–25% of GVWR on the pin, a rule of thumb, not a measurement of this unit. No truck ratings or hitch classes (why; NHTSA, DOT HS 809 433). The range starts at the published dry figure, because loaded is never lighter than dry.
03 The Pinnacle floorplan family
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 38FBRK on this page is highlighted.
| Floorplan | Nominal | Sleeps | Notable |
|---|---|---|---|
| 32RLTS | 36 ft | 4 | Rear living, kitchen island, walk-in shower |
| 36FBTS | 40 ft | 4 | Front bath, rear living, fireplace |
| 38KPTS | 41 ft | 4 | Rear living, kitchen island |
| 38SSWS | 43 ft | 4 | Rear living, kitchen island, walk-in shower |
| 38FBRK | 43 ft | 4 | Front bath, bath-and-a-half, rear kitchen |
| 39FLOK | 44 ft | 6 | Front living, outdoor kitchen, five slides |
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 Notes on this floorplan
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.
06 Loading it for a trip
A full 75-gallon fresh tank is about 626 lb of water (water counts as cargo: 49 CFR 571.120 S10.4.2), 23% of the 38FBRK’s 2,752 lb cargo capacity, leaving 2,126 lb (532 lb per rated berth). Across 11 Pinnacle floorplans the water share runs 19% to 26%, and 1 gives up more than this one. Nearest on that share: Pinnacle 36SSWS at 21% and Pinnacle 38FLWS at 26%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.120 S10.4.3).
07 Where this floorplan sits
Closest sibling: the Pinnacle 36FBTS, nearest on the published figures. It differs on 4 of the 8 fields both publish (this plan first): dry weight 15,448 lb vs 14,270 lb; GVWR 18,200 lb vs 17,500 lb; cargo capacity 2,752 lb vs 3,230 lb; dry hitch weight 2,940 lb vs 2,540 lb. They match on sleeps, fresh tank, grey tank and black tank.

11 NHTSA safety record
NHTSA holds 18 recall campaigns and 31 owner complaints against the Pinnacle line. They are counted separately: a recall is a confirmed defect with a remedy, a complaint one owner’s unverified account.
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%).
Recall coverage here is not complete, and complaints are owners’ unverified reports (how this record is built). Check a specific VIN at NHTSA before you buy. Full tables are on the Pinnacle line page.
