01 What makes it unique
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 459 pounds when full.
Tanks are 55 gallons fresh, 38 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' 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.
Specifications by model year
This floorplan has a verified factory record for 3 model years here, 2025 to 2027, and the specification does not hold still. Across those years dry weight ranges from 3,630 lb in 2026 to 3,725 lb in 2025, a spread of 95 lb; dry tongue weight ranges from 380 lb in 2025 to 410 lb in 2027, a spread of 30 lb. The factory tire size changes over the run (ST225/75R15'E' then ST225/75R15E), and the load-range letter in that code is part of the axle rating. 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.
| Model year | Dry (UVW) | GVWR | Cargo (CCC) | Dry tongue | Sleeps | Tire size |
|---|---|---|---|---|---|---|
| 2025 | 3,725 | 4,995 | 1,270 | 380 | 4 | ST225/75R15E |
| 2026 | 3,630 | 4,995 | 1,365 | 385 | 4 | ST225/75R15E |
| 2027 | 3,675 | 4,995 | 1,320 | 410 | 4 | ST225/75R15'E' |
Every row is that model year’s own record from Jayco’s model page for that year. The figures in the tow-critical placard at the top of this page are the 2027 record from the source this catalogue originally profiled. On the weights, overall length and tire size, that record and Jayco’s own 2027 model page agree on every field both of them publish. Exterior height is not compared: Jayco publishes a bare height, a with-A/C height and a with-2nd-A/C height, and the single height row carried here cannot be matched to one of them, so no claim is made either way.

Towing it
Loaded range: 10–15% of GVWR on the tongue, a rule of thumb, not a measurement of this unit. No truck ratings or hitch classes (why; NHTSA, DOT HS 809 433).
03 The Jay Feather Air floorplan family
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.
| Floorplan | Family | Type | Nominal | Sleeps | Notable |
|---|---|---|---|---|---|
| 15MRB | 2027 | TT | 20 ft | 4 | 20' 2" · 6' 6" interior · sleeps 4 |
| 16RB | 2027 | TT | 20 ft | 4 | 20' 2" · 6' 6" interior · sleeps 4 |
| 18FBS | 2027 | TT | 21 ft | 3 | 21' 4" · 6' 6" interior · sleeps 3 |
| 16DB | 2027 | TT | 22 ft | 8 | 22' 11" · 6' 6" interior · sleeps 8 |

04 Notes on this floorplan
Figures are Jayco’s own, and they tie out
Dry 3,675 lb + cargo 1,320 lb = GVWR 4,995 lb exactly. Nothing on this page is computed from the other two, estimated from the segment, or taken from a dealer listing.
Dry means empty, and you will not tow it empty
3,675 lb is the unit as built, before water, propane, batteries, cargo or dealer-installed options. Weigh the loaded trailer on a public scale before matching it to a tow vehicle.
Tongue load rides the rear axle
410 lb dry tongue transfers to the hitch and the rear axle. A weight-distributing hitch moves that load around; it does not make it disappear.
What this page does not publish
Jayco’s factory spec table for this floorplan carries no slide count, no bed size, no refrigerator or air-conditioner spec, no tire size and no MSRP. Those rows are absent here rather than filled from a sibling floorplan or a second source. Jayco’s published awning length is held in this catalogue’s saved copy of the factory page but not printed, because the catalogue tracks no awning field to print it into.
05 How it compares
Dry 3,840 lb against this plan’s 3,675 lb — 165 lb more to tow.
Every Jay Feather Air floorplan catalogued here, with the plans this site refuses to publish and the reason for each.
06 Loading it for a trip
A full 55-gallon fresh tank is about 459 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 861 lb (215 lb per rated berth). Across 44 Jay Feather floorplans the water share runs 24% 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).
07 Where this floorplan sits
Closest sibling: the Jay Feather 16RB, nearest on the published figures. It differs on 3 of the 9 fields both publish (this plan first): dry weight 3,675 lb vs 3,840 lb; cargo capacity 1,320 lb vs 1,155 lb; dry hitch weight 410 lb vs 440 lb. They match on length, sleeps, GVWR, fresh tank, grey tank and black tank.

11 NHTSA safety record
NHTSA holds 23 recall campaigns and 39 owner complaints against the Jay Feather line. They are counted separately: a recall is a confirmed defect with a remedy, a complaint one owner’s unverified account.
What to look at on a used one. Across the 39 complaints filed on this line the most-reported components are structure (21%), equipment (15%) and tires (15%).
Recall coverage here is not complete, and complaints are owners’ unverified reports (how this record is built). Check a specific VIN at NHTSA before you buy. Full tables are on the Jay Feather line page.
