Jayco Pinnacle · 2020–202537MDQS

The Pinnacle 37MDQS 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 2025 37MDQS, 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 2025 model year, which is the measurement that matters for a site pitch as well as for the road.

For the 2025 model year Jayco published a 18,400-pound GVWR on a 15,315-pound dry weight, 3,085 pounds of published cargo capacity, a 3,100-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 2025 coach left the factory on 215/75R17.5'H' tyres; the load range in that code is part of the axle rating and a replacement set has to match it.

Against the 2024 build of the same floorplan, 5 published fields moved. The full comparison is in section 02, and it is drawn from two separate verified factory records rather than from one record and an assumption about the other.

A 2025 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 37MDQS differs from the other twelve Pinnacle floorplans. Most distinctive first. Sibling pages may cover other model years than this one (2020–2025). How these ranks are worked out.

• Exterior height, 12 ft 6 in: second-lowest of twelve, between the 38SSWS (12 ft 5 in) and the 32RLTS, 36FBTS and four others (12 ft 7 in).
• Dry pin weight as a share of dry weight, 20.2%: third-largest of thirteen, between the 39FBRL (20.1%) and the 38SSWS (21.9%).
• Cargo capacity, 3,085 lb: fourth-largest of twelve, between the 36KPTS (3,080 lb) and the 39FBRL (3,130 lb).
• Length, 41 ft 8 in: fourth-shortest of eight, between the 36KPTS (41 ft 1 in) and the 38SSWS (43 ft 2 in).
• Cargo capacity as a share of GVWR, 16.8%: fifth-largest of twelve, between the 39FBRL (16.7%) and the 32RLTS and 36KPTS (17.8%).
• Dry pin weight, 3,100 lb: fifth-heaviest of thirteen, between the 39FLOK (3,095 lb) and the 39FBRL (3,130 lb).
• Sleeping capacity, 8: largest of twelve, level with the 39DSDB; next are the 38FLGS and 39FLOK (6).
• GVWR, 18,400 lb: sixth-highest of thirteen, between the 38FBRK (18,200 lb) and the 38FLGS (18,500 lb).
• Dry weight, 15,315 lb: seventh-lightest of thirteen, between the 36SSWS (14,735 lb) and the 38SSWS (15,415 lb).
• Black tank, 50 gal: shared with the 32RLTS, 36KPTS and three others; of thirteen, one smaller and six larger, nearest the 38FLWS (37 gal) and the 38FLGS and 39FLOK (74 gal).

Next to the 36SSWS (2020–2024 page), the nearest lighter floorplan by dry weight, the 37MDQS is 580 lb heavier by dry weight, has a GVWR 750 lb higher, has 170 lb more cargo capacity, has a dry pin weight 185 lb heavier, is 1 ft 8 in longer, stands 1 in lower and sleeps four more; the two publish the same interior height, fresh tank, grey tank and black tank.

Next to the 38SSWS (2025–2027 page), the nearest heavier floorplan by dry weight, the 37MDQS is 100 lb lighter by dry weight, has a GVWR 300 lb lower, has a dry pin weight 270 lb lighter, is 1 ft 6 in shorter, stands 1 in taller and sleeps four more; the two publish the same fresh tank, grey tank and black tank.

This floorplan has a published factory record for 6 model years here, 2020 to 2025. The specification does not hold still: GVWR runs from 16,995 lb (2020) to 18,400 lb (2025); dry weight runs from 14,250 lb (2020) to 15,315 lb (2025); dry pin weight runs from 2,885 lb (2023) to 3,370 lb (2022). The published tire size changes over the run (ST255/85R16'E', then 215/75R17.5'H'). The published sleeping capacity changes across the years: 6 - 8 in 2020, 6-8 in 2021, 5-7 in 2022, up to 10 in 2023, up to 8 in 2024–2025. Each year’s complete record is printed separately below, carrying only that year’s own published figures and source. Nothing is copied across from a neighbouring year.

Jayco changed 5 of the published fields between the 2024 and 2025 37MDQS. Every figure in both columns is that model year's own factory record — nothing here is carried across from the 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), 20% of the 37MDQS’s 3,085 lb cargo capacity, leaving 2,462 lb (308 lb per rated berth). Across 13 Pinnacle floorplans the water share runs 19% to 26%, and 8 give up more than this one. Nearest on that share: Pinnacle 39FBRL at 20% and Pinnacle 36KPTS at 20%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.120 S10.4.3).
