Jayco · 2026–2027Jay Flight 180LK

The Jay Flight 180LK is the 15th-lightest of the 56 MY2027 Jay Flight floorplans this site carries from Jayco’s own 2027 model pages, with 14 plans below it and 41 above. Its 3,555 lbs dry and 4,800 lbs GVWR leave 1,245 lbs of cargo capacity — 26% of the loaded rating, which is the figure that actually decides what you can put in it.

Fresh water is the load most owners forget to count. The 30 gallon fresh tank weighs about 249 lbs full, which is 20% of this plan's 1,245 lbs of cargo capacity before a single bag goes in. Grey and black hold 20 and 20 gallons. Travelling with full fresh and empty waste tanks is the arrangement that leaves the most room for everything else.

It runs a single axle, as Jayco's own factory page for this floorplan reports.

This floorplan has a published factory record for 2 model years here, 2026 to 2027. The specification does not hold still: dry weight runs from 3,555 lb (2027) to 3,560 lb (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.

All 56 MY2027 Jay Flight floorplans this site carries, ordered lightest to heaviest by published dry weight. Jayco markets 2027 as the line's 25th-anniversary year. Floorplans whose code ends in W are built at Jayco's western plant and carry their own published figures — they are not duplicates of the eastern build.

A full 30-gallon fresh tank is about 249 lb of water (water counts as cargo: 49 CFR 571.110 S9.3.2), 20% of the Jay Flight 180LK’s 1,245 lb cargo capacity, leaving 996 lb (249 lb per rated berth). Across 123 Jay Flight floorplans the water share runs 13% to 47%, and 113 give up more than this one. Nearest on that share: Jay Flight 197MBW at 20% and Jay Flight 175FQ at 20%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.110 S9.3.3).
