Jayco Jay Feather Micro · 2021–2025166FBS

The Jayco Jay Feather Micro 166FBS is a 19' 7" travel trailer in the MY2025 Jay Feather Micro roster. Jayco publishes a dry weight of 3,925 pounds against a 4,995-pound GVWR, and the two tie out exactly with the published 1,070-pound cargo carrying capacity — 3,925 + 1,070 = 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 475 pounds, or 12% 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 1,070 pounds, 21% 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, 30 grey and 30 black. Interior height is 6' 6" and the exterior measures 7' 6" wide. Jayco publishes two exterior heights for this floorplan: 9' 11" at the roofline and 10' 6" 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 MY2025 166FBS 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 166FBS differs from the other 46 Jay Feather floorplans. Most distinctive first. Sibling pages may cover other model years than this one (2021–2025). How these ranks are worked out.

Next to the 18FBS (2026–2027 page), the nearest lighter floorplan by dry weight, the 166FBS is 45 lb heavier by dry weight, has 45 lb less cargo capacity, has a dry tongue weight 35 lb heavier, is 1 ft 9 in shorter, stands 5 in taller, has a grey tank 0.5 gal smaller, has a black tank 0.5 gal smaller and sleeps one more; the two publish the same GVWR, interior height and fresh tank.

Next to the 183FBS (2025 page), the nearest heavier floorplan by dry weight, the 166FBS is 5 lb lighter by dry weight, has 5 lb more cargo capacity, has a dry tongue weight 70 lb heavier, is 1 ft 3 in shorter, stands 1 in taller and sleeps one more; the two publish the same GVWR, interior height, fresh tank, grey tank and black tank.

This floorplan has a published factory record for 5 model years here, 2021 to 2025. The specification does not hold still: dry weight runs from 3,895 lb (2024) to 4,035 lb (2021); dry tongue weight runs from 415 lb (2024) to 480 lb (2021). The published sleeping capacity changes across the years: 3-4 in 2021, 3 in 2022, up to 3 in 2023–2024, up to 4 in 2025. 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 Micro was the smallest roster Jayco built under the Jay Feather name. Jayco's own floorplan index publishes Micro plans for MY2023 through MY2025 and no later model year, so the figures on this page are the last ones Jayco published for this floorplan. It is a factory sub-roster and is catalogued under the Jay Feather line hub. The 166FBS 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), 43% of the 166FBS’s 1,070 lb cargo capacity, leaving 614 lb (153 lb per rated berth). Across 47 Jay Feather floorplans the water share runs 23% to 43%, and 1 gives up more than this one. Nearest on that share: Jay Feather 18FBS at 41% and Jay Feather 183FBS at 43%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.110 S9.3.3).
