2027 Jayco Jay Flight Bungalow401FLTS

The Jayco Jay Flight Bungalow 401FLTS is a 40' 4" destination trailer in the MY2027 Jay Flight Bungalow roster. Jayco publishes a dry weight of 10,355 pounds against a 12,000-pound GVWR, and the two tie out exactly with the published 1,645-pound cargo carrying capacity — 10,355 + 1,645 = 12,000. 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 1,515 pounds, or 15% 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 1,645 pounds, 14% of GVWR — that is the ceiling for water, propane, cargo and any dealer-fitted equipment combined. Fresh water alone at 52 gallons is about 432 pounds when full.

Tanks are 52 gallons fresh, 39 grey and 39 black. Interior height is 8' 0" and the exterior measures 8' 0" wide. Jayco publishes two exterior heights for this floorplan: 12' 0" at the roofline and 12' 7" 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 401FLTS 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.

Jay Flight Bungalow is Jayco's destination-trailer roster inside the Jay Flight family — forty-foot-plus units built to be towed to a seasonal site and left there. Jayco's own floorplan index titles the roster a spacious destination travel trailer. It is a factory sub-roster of Jay Flight and is catalogued under the Jay Flight line hub. The 401FLTS on this page is highlighted; every other profiled plan links to its own page.

A full 52-gallon fresh tank is about 432 lb of water (water counts as cargo: 49 CFR 571.120 S10.4.2), 26% of the 401FLTS’s 1,645 lb cargo capacity, leaving 1,213 lb (303 lb per rated berth). Across 123 Jay Flight floorplans the water share runs 13% to 47%, and 62 give up more than this one. Nearest on that share: Jay Flight 130RD at 26% and Jay Flight 245BHS at 26%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.120 S10.4.3).
