Jayco Pinnacle · 202038FLWS

The Pinnacle 38FLWS is one of Jayco's Pinnacle coaches, the flagship of the Jayco towable lineup, above the North Point and Eagle fifth wheels. This page covers one model year of it — the 2020 38FLWS, exactly as Jayco published it — because the numbers that decide whether your truck can pull this trailer are not the same from one year to the next.

For the 2020 model year Jayco published a 16,995-pound GVWR on a 14,275-pound dry weight, 2,720 pounds of published cargo capacity, a 4,225-pound dry pin weight. A pin weight in that range lands well outside half-ton territory: plan on a three-quarter-ton or larger truck, and check the loaded pin against the truck's payload and rear-axle ratings rather than against the tow rating alone.

This is the earliest 38FLWS model year with a verified factory record in this catalogue. Later years are linked at the foot of the page, each with its own published figures.

A 2020 coach is 6 model years old as of 2026, which puts it squarely in used-buyer territory. Section 05 sets out what to inspect on a laminated-wall fifth wheel of this age — tyre date codes, roof and seam sealant, slide seals, and the soft-floor and delamination checks that separate a tidy coach from an expensive one.

2020 is the only model year this catalogue holds a verified factory record for the 38FLWS. That record is published here on its own, and it is not a general specification for the floorplan: Jayco revises published weights, ratings and even tire sizes from one model year to the next, so every figure below is evidence about 2020 and about no other year.

This floorplan carries its water comfortably. A full 85-gallon fresh tank is roughly 26% of the 2,720-pound cargo capacity, leaving the 38FLWS with a usable gear budget even when you tow full.

The published dry pin weight of 4,225 pounds is 30% of this floorplan’s 14,275-pound dry weight. Fifth-wheel pin weight rides in the bed of the truck, so it comes off payload rather than off tow rating — and it rises with the trailer as you load it, not in proportion to what you put over the axles.

Nothing above changes the ceiling. Loaded to its 16,995-pound GVWR the 38FLWS is towing 2,720 pounds more than its 14,275-pound dry figure, and that is the number your vehicle has to be rated for — not the brochure weight.

Ranked by GVWR, the 38FLWS sits 2 of 11 in the Pinnacle line: 16,995 pounds against a line that runs from 16,600 to 18,800 pounds. That position is the useful thing to know, because the plans immediately either side of it are the real alternatives.

Either side of it in the same line: Pinnacle 32RLTS is 395 pounds lighter at 16,600 lb GVWR; and Pinnacle 36KPTS is 355 pounds heavier at 17,350 lb GVWR.

Against the 38FLWS: the Model Z 3300 sleeps 1 more; the North Point 340CKTS is 5 lb heavier and sleeps 1 fewer; the Vengeance Rogue 341GS11 is 5 lb lighter. Those are differences in the published numbers only — what they cost, how they are built and how they live are separate questions each of those pages answers on its own terms.

Those are the nearest fifth wheels from other lines by weight — one per line, picked by proximity on that figure and nothing else. They are listed so the same tow vehicle can be checked against real alternatives, not because they are equivalent inside; layout, build and price diverge sharply across that group.

For scale, the Pinnacle floorplans profiled here run 13,645 to 15,870 pounds dry and 40 to 44 feet of exterior length across 11 plans. Where a floorplan falls in that spread usually says more about which vehicle can tow it, and which site it fits, than the layout name does.

Every profiled floorplan in this line, with the full weight table, is on the Pinnacle line hub.

This catalog tracks 18 specification fields per floorplan. Named sources publish 9 of them for the 38FLWS. The rest are not shown, because the alternative is reading a figure across from a sibling floorplan or from what the segment usually does — and a number nobody published is worth less than an admitted gap.

Not published for this floorplan: exterior length, exterior height, grey tank, slide count, axle count, tire specification, awning, refrigerator, air conditioning. If you find one of these in a manufacturer document for this plan, it belongs on this page.

The completeness figure at the foot of this page (48%) measures the same thing on the full field set: it is a measurement of how much this floorplan’s manufacturer publishes, not of how much research went into the page.

How every figure here was sourced and checked is set out on the methodology page.
