Jayco Pinnacle · 202739DSDB

The Pinnacle 39DSDB 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 2027 39DSDB, 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. Jayco publishes it at 8' 6" wide closed and 14' 6" with the slide-outs run out for the 2027 model year, which is the measurement that matters for a site pitch as well as for the road.

For the 2027 model year Jayco published a 19,200-pound GVWR on a 16,360-pound dry weight, 2,840 pounds of published cargo capacity, a 3,170-pound dry pin weight. Check the loaded pin against the truck's payload and rear-axle ratings rather than against the tow rating alone. The 2027 coach left the factory on ST215/75R17.5'H' tyres; the load range in that code is part of the axle rating and a replacement set has to match it.

This is the only 39DSDB model year with a verified factory record in this catalogue.

A 2027 coach is close to current as of 2026, but section 05 still applies: check it against its build date rather than its model year. Jayco commonly builds a model year well before the calendar year turns, and the tyre date codes have to be read against the build month, not the badge.

How the 39DSDB differs from the other twelve Pinnacle floorplans. Most distinctive first. Each rank counts only the siblings that publish that field, and a figure most of them share is left out. Not every one of these pages covers the same model years as this one (2027); each figure is the one its own page prints, so a rank compares pages, not one model year.

• Dry weight, 16,360 lb: heaviest of thirteen; next is the 39FLOK (15,870 lb).
• GVWR, 19,200 lb: highest of thirteen; next is the 39FLOK (18,800 lb).
• Cargo capacity as a share of GVWR, 14.8%: smallest of twelve; next is the 38FBRK (15.1%).
• Grey tank, 124 gal: largest of twelve; next are the 32RLTS, 36FBTS and seven others (87 gal).
• Cargo capacity, 2,840 lb: third-smallest of twelve, between the 38FBRK (2,752 lb) and the 36SSWS (2,915 lb).
• Dry pin weight, 3,170 lb: third-heaviest of thirteen, between the 39FBRL (3,130 lb) and the 38SSWS (3,370 lb).
• Dry pin weight as a share of dry weight, 19.4%: fourth-smallest of thirteen, between the 38FBRK (19%) and the 36KPTS and 39FLOK (19.5%).
• Sleeping capacity, 8: largest of twelve, level with the 37MDQS; next are the 38FLGS and 39FLOK (6).
• Black tank, 87 gal: largest of thirteen, level with the 36FBTS, 38FBRK and 39FBRL; next are the 38FLGS and 39FLOK (74 gal).

Next to the 39FLOK (2026–2027 page), the nearest lighter floorplan by dry weight, the 39DSDB is 490 lb heavier by dry weight, has a GVWR 400 lb higher, has 90 lb less cargo capacity, has a dry pin weight 75 lb heavier, stands 8 in lower, has a grey tank 41.5 gal larger, has a black tank 13 gal larger and sleeps two more; the two publish the same fresh tank.

2027 is the only model year this catalogue holds a verified factory record for the 39DSDB. 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 2027 and about no other year.

A full 75-gallon fresh tank is about 622 lb of water (water counts as cargo: 49 CFR 571.120 S10.4.2), 22% of the 39DSDB’s 2,840 lb cargo capacity, leaving 2,218 lb (277 lb per rated berth). Across 13 Pinnacle floorplans the water share runs 19% to 26%, and 2 give up more than this one. Nearest on that share: Pinnacle 36SSWS at 21% and Pinnacle 38FBRK at 23%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.120 S10.4.3).

Closest sibling: the Pinnacle 39FLOK, nearest on the published figures. It differs on 7 of the 8 fields both publish (this plan first): sleeps 8 vs 6; dry weight 16,360 lb vs 15,870 lb; GVWR 19,200 lb vs 18,800 lb; cargo capacity 2,840 lb vs 2,930 lb; hitch weight 3,170 lb vs 3,095 lb; grey tank 124 gal vs 82.5 gal; black tank 87 gal vs 74 gal. They match on fresh tank.

Either side of it by GVWR: Pinnacle 39FLOK is 400 lb lighter (18,800 lb GVWR).

All 13 Pinnacle floorplans: Pinnacle line hub.

Against the 39DSDB: the Riverstone 38BMB is 50 lb heavier; the Influence 3804DS is 200 lb lighter and sleeps 2 fewer; the Momentum 344M is 200 lb lighter and sleeps 2 fewer.
