Jayco Jay Flight SLX · 2025–2026290RKS

The Jayco Jay Flight SLX 290RKS is a 36' 10" travel trailer in the MY2026 Jay Flight SLX roster. Jayco publishes a dry weight of 7,810 pounds against a 9,650-pound GVWR, and the two tie out exactly with the published 1,840-pound cargo carrying capacity — 7,810 + 1,840 = 9,650. 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 1,080 pounds, or 14% 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 1,840 pounds, 19% 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, 110.5 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' 3" 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 290RKS 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 290RKS 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.

• Dry weight, 7,810 lb: heaviest of 36; next is the 324BDS (7,615 lb).
• GVWR, 9,650 lb: highest of 36; next is the 280FKS (9,500 lb).
• Dry tongue weight, 1,080 lb: heaviest of 36; next is the 324BDS (940 lb).
• Dry tongue weight as a share of dry weight, 13.8%: largest of 36; next is the 284BHS (13.5%).
• Length, 36 ft 10 in: longest of 36; next is the 324BDS (36 ft 2 in).
• Grey tank, 110.5 gal: second-largest of 36, between the 235RKS, 237RBS and two others (78 gal) and the 280FKS (117 gal).
• Cargo capacity, 1,840 lb: sixth-largest of 35, between the 245RLS (1,780 lb) and the 265BHS (1,870 lb).
• Exterior height, 10 ft 7 in: shared with the 280FKS; of sixteen, thirteen lower and one taller, nearest the 265BHS and 287BHSW (10 ft 6 in) and the 286BHSW (10 ft 8 in).
• Cargo capacity as a share of GVWR, 19.1%: seventh-smallest of 35, between the 298BH (18.3%) and the 224BH (19.4%).
• Fresh tank, 52 gal: shared with the 211MB, 265BHS and three others; of 35, 25 smaller and four larger, nearest the 212QB, 224BH and two others (48 gal) and the 265BHSW, 284BHSW and two others (76 gal).
• Sleeping capacity, 5: shared with the 174BHW; of eighteen, eight smaller and eight larger, nearest the 160LK, 160LKW and two others (4) and the 184BSW and 211MB (6).

Next to the 324BDS (2018 page), the nearest lighter floorplan by dry weight, the 290RKS is 195 lb heavier by dry weight, has a GVWR 650 lb higher, has 455 lb more cargo capacity, has a dry tongue weight 140 lb heavier, is 8 in longer, has a fresh tank 6 gal larger and has a grey tank 69.5 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: GVWR runs from 9,500 lb (2025) to 9,650 lb (2026); dry weight runs from 7,710 lb (2025) to 7,810 lb (2026); dry tongue weight runs from 1,080 lb (2026) to 1,093 lb (2025). The published sleeping capacity changes across the years: up to 2 in 2025, up to 5 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 290RKS 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), 23% of the 290RKS’s 1,840 lb cargo capacity, leaving 1,408 lb (282 lb per rated berth). Across 34 Jay Flight SLX floorplans the water share runs 18% to 39%, and 20 give up more than this one. Nearest on that share: Jay Flight SLX 265BHS at 23% and Jay Flight SLX 211MB at 24%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.110 S9.3.3).
