01 What makes the 2024 40DLFT different
The Jay Flight Bungalow 40DLFT is one of Jayco's Jay Flight Bungalow destination trailers, the largest and most residential end of the Jay Flight range, built to be parked for a season rather than moved every weekend.
Across the 4 model years of the 40DLFT on this site (2023 to 2026), the 2024 record has the lightest dry weight, 12,025 lbs; the lowest GVWR, 14,000 lbs (level with 2023); cargo capacity 1,975 lbs, between 1,925 lbs (2023) and 2,070 lbs (2026); the heaviest dry tongue weight, 1,600 lbs; the shortest exterior length, 41' 5" (level with 2023).
Against the 2025 40DLFT, the next model year on this site, 8 of the 19 fields both records publish differ: dry weight 12,025 lbs to 12,450 lbs (+425 lb); GVWR 14,000 lbs to 14,500 lbs (+500 lb); cargo capacity 1,975 lbs to 2,050 lbs (+75 lb); dry tongue weight 1,600 lbs to 1,550 lbs (-50 lb); exterior length 41' 5" to 41' 6" (+1 in); exterior height 12' 10" to 12' 11" (+1 in); height with A/C 13' 0" to 13' 1" (+1 in); fresh tank 52.0 gal to 51.0 gal (-1 gal).
Among the 4 Jayco Jay Flight Bungalow travel trailers with a 2024 page on this site, the 40DLFT is the heaviest of 4 by dry weight; the highest of 4 by GVWR; 2nd smallest of 4 by cargo capacity; the longest of 4 by exterior length. By dry weight, the lightest is the 40FKDS at 10,510 lbs.

Federal tire recalls naming this size. NHTSA’s recall file names ST235/80R16 in one tire recall: 21T018000 (Sailun Tire Americas, Inc., 2021; make SAILUN; models BLACKHAWK, BLACKLION, IRONHEAD, ROADX, SAILUN). A tire recall covers only the brands, lines and DOT date codes it lists, and this page does not know which brand of tire this trailer was built with, so read the brand and DOT code on your own sidewalls before relying on this list. Only 242 of NHTSA’s 788 tire recalls name a size in their summary, so a size with no match is not a clean record (NHTSA recall file, read 12 Oct 2026).

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). The range starts at the published dry figure, because loaded is never lighter than dry.
03 What changed for the 2024 model year
