Jayco Pinnacle · 2025–202738SSWS

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.

This floorplan has a verified factory record for 3 model years here, 2025 to 2027, and the specification does not hold still. Across those years dry weight ranges from 15,290 lb in 2025 to 15,625 lb in 2027, a spread of 335 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.

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 38SSWS on this page is highlighted.

A full 75-gallon fresh tank is about 626 lb of water (water counts as cargo: 49 CFR 571.120 S10.4.2), 19% of the 38SSWS’s 3,350 lb cargo capacity, leaving 2,724 lb (681 lb per rated berth). Across 11 Pinnacle floorplans the water share runs 19% to 26%, and this plan’s is the lowest. Nearest on that share: Pinnacle 36FBTS at 19%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.120 S10.4.3).

Closest sibling: the Pinnacle 38KPTS, nearest on the published figures. It differs on 5 of the 9 fields both publish (this plan first): length 43 ft 1 in vs 41 ft 0 in; dry weight 15,415 lb vs 14,535 lb; GVWR 18,700 lb vs 17,700 lb; cargo capacity 3,350 lb vs 3,165 lb; dry hitch weight 3,370 lb vs 2,870 lb. They match on sleeps, fresh tank, grey tank and black tank.

Either side of it by GVWR: Pinnacle 38FLGS is 200 lb lighter (18,500 lb GVWR); Pinnacle 39FLOK is 100 lb heavier (18,800 lb GVWR).

All 11 Pinnacle floorplans: Pinnacle line hub.
