Jayco Jay Flight SLX · 2025–2026280FKS

The Jayco Jay Flight SLX 280FKS is a 33' 10" travel trailer in the MY2026 Jay Flight SLX roster. Jayco publishes a dry weight of 7,465 pounds against a 9,500-pound GVWR, and the two tie out exactly with the published 2,035-pound cargo carrying capacity — 7,465 + 2,035 = 9,500. That arithmetic is checked on every plan in this catalogue, and a plan whose own figures disagree is catalogued without a page rather than quietly reconciled.

The dry tongue weight is 720 pounds, or 10% of the dry weight. Tongue load transfers to the hitch and the rear axle, and a weight-distributing hitch redistributes it rather than removing it. Payload is 2,035 pounds, 21% of GVWR — that is the ceiling for water, propane, cargo and any dealer-fitted equipment combined. Fresh water alone at 52 gallons is about 432 pounds when full.

Tanks are 52 gallons fresh, 117 grey and 39 black. Interior height is 6' 9" and the exterior measures 8' 0" wide. Jayco publishes two exterior heights for this floorplan: 10' 7" at the roofline and 11' 0" with the air conditioner. Both are printed above, neither is derived from the other, and it is the taller figure that has to clear your garage. This page covers the MY2026 280FKS only. Jayco’s figures move between model years — measured on one Jayco floorplan across five consecutive years, 20 of 28 published fields changed, including a 290-pound swing in dry hitch weight — so nothing here is carried over from a neighbouring year, and no year is shown that Jayco has not published for this code.

How the 280FKS differs from the other 35 Jay Flight SLX floorplans. Most distinctive first. Sibling pages may cover other model years than this one (2025–2026). How these ranks are worked out.

• Cargo capacity as a share of GVWR, 21.4%: shared with the 235RKS; of 35, ten smaller and 23 larger, nearest the 145RB (20.5%) and the 294QBS (21.5%).

Next to the 294QBS (2018 page), the nearest lighter floorplan by dry weight, the 280FKS is 985 lb heavier by dry weight, has a GVWR 1,250 lb higher, has 265 lb more cargo capacity, has a dry tongue weight 60 lb lighter, is 1 ft 7 in shorter, has a fresh tank 8 gal larger and has a grey tank 69.5 gal larger; the two publish the same interior height.

Next to the 324BDS (2018 page), the nearest heavier floorplan by dry weight, the 280FKS is 150 lb lighter by dry weight, has a GVWR 500 lb higher, has 650 lb more cargo capacity, has a dry tongue weight 220 lb lighter, is 2 ft 4 in shorter, has a fresh tank 6 gal larger and has a grey tank 76 gal larger; the two publish the same interior height.

This floorplan has a published factory record for 2 model years here, 2025 to 2026. The specification does not hold still: dry weight runs from 7,455 lb (2025) to 7,465 lb (2026); dry tongue weight runs from 720 lb (2026) to 830 lb (2025). The published sleeping capacity changes across the years: up to 4 in 2025, up to 3 in 2026. 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.

Jay Flight SLX was Jayco's value travel-trailer range through MY2026, spanning single-axle compacts to family bunkhouses. For MY2027 Jayco folded the range into the Jay Flight name, so floorplans that carried on into 2027 are catalogued under that badge and the plans profiled here are the ones SLX published and Jay Flight did not. Western builds carry a W suffix. The 280FKS on this page is highlighted; every other profiled plan links to its own page.

A full 52-gallon fresh tank is about 432 lb of water (water counts as cargo: 49 CFR 571.110 S9.3.2), 21% of the 280FKS’s 2,035 lb cargo capacity, leaving 1,603 lb (534 lb per rated berth). Across 34 Jay Flight SLX floorplans the water share runs 18% to 39%, and 27 give up more than this one. Nearest on that share: Jay Flight SLX 294QBS at 21% and Jay Flight SLX 145RB at 22%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.110 S9.3.3).
