01 What makes it unique
The 38KPTS is the stretched rear-living Pinnacle: the same rear living area and walk-around kitchen island as the 32RLTS, opened out to 41 feet for more room in the lounge and galley, with a king bedroom up front. It runs 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 a 17,700-pound GVWR against the 14,535-pound dry weight, leaving a 3,165-pound cargo capacity and a 2,870-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 75/87/50-gallon fresh/grey/black tanks are standard. At a starting MSRP around $129,000, with street pricing below placard, the 38KPTS is the rear-living Pinnacle for buyers who want the couples’ layout with more length and living space and tow with a properly rated three-quarter-ton or one-ton truck.
Specifications by model year
This floorplan has a verified factory record for 2 model years here, 2025 to 2026. 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 |
|---|---|---|---|---|---|---|
| 2025 | 14,535 | 17,700 | 3,165 | 2,870 | 4 | 215/75R17.5'H' |
| 2026 | 14,535 | 17,700 | 3,165 | 2,870 | 4 | 215/75R17.5'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 38KPTS 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 living with more length
The 32RLTS rear-living, kitchen-island format stretched to 41 feet — more room in the lounge and galley.
Walk-around island kitchen
An amidships galley with a walk-around island and the line-standard GE Profile range and 21-cu-ft 12V refrigerator.
Full luxury equipment
Carries the complete Pinnacle standard package on the flagship 102-inch wide-body chassis.
Wants a three-quarter-ton+ truck
A 17,700-pound-GVWR full-profile fifth wheel — confirm a properly rated three-quarter-ton or one-ton truck’s payload and rear axle.
05 How it compares
Grand Design’s luxury rear-kitchen Solitude — a comparable full-profile luxury-5W cross-shop.
The rear-living 32RLTS — the same format, shorter and lighter.
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), 20% of the 38KPTS’s 3,165 lb cargo capacity, leaving 2,540 lb (635 lb per rated berth). Across 11 Pinnacle floorplans the water share runs 19% to 26%, and 8 give up more than this one. Nearest on that share: Pinnacle 36FBTS at 19% and Pinnacle 37MDQS at 20%. 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

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.
