Jayco Jay Feather Air · 2025–202715MRB

The Jayco Jay Feather Air 15MRB is a 20' 2" travel trailer in the MY2027 Jay Feather Air roster. Jayco publishes a dry weight of 3,675 pounds against a 4,995-pound GVWR, and the two tie out exactly with the published 1,320-pound cargo carrying capacity — 3,675 + 1,320 = 4,995. 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 410 pounds, or 11% 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 1,320 pounds, 26% of GVWR — that is the ceiling for water, propane, cargo and any dealer-fitted equipment combined. Fresh water alone at 55 gallons is about 457 pounds when full.

Tanks are 55 gallons fresh, 38 grey and 30.5 black. Interior height is 6' 6" and the exterior measures 8' 0" wide. Jayco publishes two exterior heights for this floorplan: 9' 8" at the roofline and 10' 5" 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 15MRB 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 15MRB differs from the other 46 Jay Feather floorplans. Most distinctive first. Sibling pages may cover other model years than this one (2025–2027). How these ranks are worked out.

Next to the 17RBSL (2027 page), the nearest lighter floorplan by dry weight, the 15MRB is 755 lb heavier by dry weight, has a GVWR 1,245 lb higher, has 490 lb more cargo capacity, has a dry tongue weight 100 lb heavier, is 1 ft 5 in shorter, stands 4 in taller, has a fresh tank 25 gal larger, has a grey tank 18 gal larger and has a black tank 0.5 gal larger; the two publish the same interior height and sleeping capacity.

Next to the 171BH (2021–2025 page), the nearest heavier floorplan by dry weight, the 15MRB is 75 lb lighter by dry weight, has 75 lb more cargo capacity, has a dry tongue weight 35 lb lighter, stands 2 in lower, has a grey tank 8 gal larger, has a black tank 0.5 gal larger and sleeps one fewer; the two publish the same GVWR, length, interior height and fresh tank.

This floorplan has a published factory record for 3 model years here, 2025 to 2027. The specification does not hold still: dry weight runs from 3,630 lb (2026) to 3,725 lb (2025); dry tongue weight runs from 380 lb (2025) to 410 lb (2027). The published tire size changes over the run (ST225/75R15E, then ST225/75R15'E'). 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 Feather Air is the lightest end of the Jay Feather range — Jayco's own floorplan index titles it lightweight travel trailers for easy towing. It is a factory sub-roster of Jay Feather, so it is catalogued under the Jay Feather line hub rather than given a hub of its own. The 15MRB on this page is highlighted; every other profiled plan links to its own page.

A full 55-gallon fresh tank is about 457 lb of water (water counts as cargo: 49 CFR 571.110 S9.3.2), 35% of the 15MRB’s 1,320 lb cargo capacity, leaving 864 lb (216 lb per rated berth). Across 47 Jay Feather floorplans the water share runs 23% to 43%, and 10 give up more than this one. Nearest on that share: Jay Feather 24RL at 34% and Jay Feather 18MBH at 35%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.110 S9.3.3).
