Jayco Jay Feather Air SL · 2026–202715TBSL

The Jayco Jay Feather Air SL 15TBSL is a 17' 6" travel trailer in the MY2027 Jay Feather Air SL roster. Jayco publishes a dry weight of 2,515 pounds against a 3,500-pound GVWR, and the two tie out exactly with the published 985-pound cargo carrying capacity — 2,515 + 985 = 3,500. 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 230 pounds, or 9% 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 985 pounds, 28% of GVWR — that is the ceiling for water, propane, cargo and any dealer-fitted equipment combined. Fresh water alone at 30 gallons is about 250 pounds when full.

Tanks are 30 gallons fresh, 20 grey and 30 black. Interior height is 6' 6" and the exterior measures 8' 0" wide. Jayco publishes two exterior heights for this floorplan: 9' 5" at the roofline and 10' 1" 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 MY2027 15TBSL 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.

This floorplan has a verified factory record for 2 model years here, 2026 to 2027, and the specification does not hold still. Across those years dry weight ranges from 2,515 lb in 2027 to 2,615 lb in 2026, a spread of 100 lb. That is why each model year has its own page below, carrying only its own published figures. Nothing on a year page is copied across from a neighbouring year.

Jay Feather Air SL is the shortest roster inside the Jay Feather range; Jayco's own floorplan index titles it a lightweight travel trailer for adventure. It is a factory sub-roster of Jay Feather and is catalogued under the Jay Feather line hub. Published lengths and dry weights for every profiled plan are in the table below. The 15TBSL on this page is highlighted; every other profiled plan links to its own page.

A full 30-gallon fresh tank is about 250 lb of water (water counts as cargo: 49 CFR 571.110 S9.3.2), 25% of the 15TBSL’s 985 lb cargo capacity, leaving 735 lb (367 lb per rated berth). Across 44 Jay Feather floorplans the water share runs 24% to 43%, and 41 give up more than this one. Nearest on that share: Jay Feather 28RB at 24% and Jay Feather 30RKB at 26%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.110 S9.3.3).
