01 What makes it unique
The 38SSWS is a rear-living Pinnacle built around a spacious walk-in shower and a rear living area, with a walk-around kitchen island amidships and a king bedroom up front. At 43 feet on three slide-outs it is one of the longer rear-living plans in the line, sleeping 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 18,700-pound GVWR against the 15,415-pound dry weight, with a factory cargo capacity of 3,350 pounds and a 3,370-pound dry pin. (The factory CCC does not reconcile with the GVWR minus dry weight, which works out to 3,285 pounds, a 65-pound difference — it is flagged in the specifications below; the GVWR and dry weight are shown as published.) 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 $137,000, with street pricing below placard, the 38SSWS is the rear-living Pinnacle for buyers who want a large walk-in shower in a longer luxury 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
Spacious walk-in shower
A rear-living plan built around a large walk-in shower, with a walk-around island kitchen and a front king suite.
Longer rear-living coach
At 43 feet it is one of the longest rear-living Pinnacles — more room throughout at a heavier 3,370-pound pin.
Cargo figure flagged
Jayco’s published 3,350-pound CCC does not reconcile with GVWR minus dry weight (3,285 pounds) by 65 pounds; the GVWR and dry weight are shown as published and the CCC is flagged.
Wants a one-ton truck
At an 18,700-pound GVWR and a 3,370-pound pin, confirm a properly rated one-ton truck’s payload and rear-axle rating.
05 How it compares
Keystone’s luxury Montana — a full-profile fifth wheel in the same length and tier.
The independent maker’s rear-kitchen luxury coach — a comparable long full-profile cross-shop.
The 38KPTS — the same rear-living format, shorter and lighter with a cleaner cargo figure.
