01 What makes the 2024 331BTS different
The Jay Flight 331BTS is one of Jayco's Jay Flight travel trailers, the mass-market nameplate and the volume seller in Jayco's towable range.
Across the 3 model years of the 331BTS on this site (2023 to 2025), the 2024 record has dry weight 8,635 lbs, between 8,465 lbs (2023) and 8,680 lbs (2025); the lowest GVWR, 9,995 lbs (level with 2023); the smallest cargo capacity, 1,360 lbs; dry tongue weight 1,210 lbs, between 1,085 lbs (2023) and 1,235 lbs (2025); the same exterior length as every other year that publishes one (37' 10").
Against the 2025 331BTS, the next model year on this site, 8 of the 20 fields both records publish differ: dry weight 8,635 lbs to 8,680 lbs (+45 lb); GVWR 9,995 lbs to 10,400 lbs (+405 lb); cargo capacity 1,360 lbs to 1,720 lbs (+360 lb); dry tongue weight 1,210 lbs to 1,235 lbs (+25 lb); width with slides out 11' 0" to 10' 6" (-6 in); exterior height 10' 7" to 10' 9" (+2 in); height with A/C 11' 3" to 11' 4" (+1 in); sleeping count up to 8 to up to 12.
Among the 42 Jayco Jay Flight travel trailers with a 2024 page on this site, the 331BTS is 3rd heaviest of 42 by dry weight; joint 3rd highest of 42 by GVWR; 18th smallest of 42 by cargo capacity; joint longest of 42 by exterior length. By dry weight, the lightest is the 154BH at 2,690 lbs and the heaviest is the 340RLK at 8,890 lbs.

Federal tire recalls naming this size. NHTSA’s recall file names ST225/75R15 in 2 tire recalls: 14T015000 (Dynamic Tire Corp., 2014; make TOWMAX STR; model ST); 17T014000 (Triangle Tire USA, 2017; make TRIANGLE; model TR643). 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.

Between the 2023 and 2024 331BTS, 9 of the 20 fields both records publish differ: dry weight, cargo capacity, dry tongue weight, width with slides out, exterior height, fresh tank, grey tank, black tank and optional propane. The other 11 match, including GVWR.
