01 What makes the 2024 40LSDL different
The Jay Flight Bungalow 40LSDL 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. This page covers one model year of it — the 2024 40LSDL, exactly as Jayco published it — because the numbers that decide whether your truck can pull this trailer are not the same from one year to the next. Jayco publishes it at 8' 6" wide closed and 11' 0" with the slide-outs run out for the 2024 model year, which is the measurement that matters for a site pitch as well as for the road.
For the 2024 model year Jayco published a 14,000-pound GVWR on a 11,940-pound dry weight, 2,060 pounds of published cargo capacity, a 10,105-pound dry tongue weight. That tongue figure is flagged on this page: it is printed as Jayco published it, it cannot be squared with the dry weight, and no ratio or hitch advice is built on it. Weigh the loaded tongue and check it against the hitch receiver's rating and the tow vehicle's payload, not against the tow rating alone. The 2024 trailer left the factory on ST235/80R16'E' tyres; the load range in that code is part of the axle rating and a replacement set has to match it.
This is the only 40LSDL model year with a verified factory record in this catalogue.
A 2024 trailer is close to current as of 2026, but section 05 still applies: check it against its build date rather than its model year. Jayco commonly builds a model year well before the calendar year turns, and the tyre date codes have to be read against the build month, not the badge.
How the 40LSDL differs from the other 122 Jay Flight floorplans. Most distinctive first. Sibling pages may cover other model years than this one (2024). How these ranks are worked out.
- Dry weight, 11,940 lb: third-heaviest of 123, between the 40LOFT (11,925 lb) and the JAYLOFT (12,360 lb).
- GVWR, 14,000 lb: third-highest of 123, between the 40LOFT (13,950 lb) and the JAYLOFT (14,300 lb).
- Length, 41 ft 11 in: shared with the JAYLOFT; of 123, 119 shorter and two longer, nearest the 402DLFT and 40DLFT (41 ft 6 in) and the 401LOFT and 404LOFT (42 ft).
- Exterior height, 12 ft 4 in: seventh-tallest of 109, between the 255THW (12 ft 2 in) and the 40LOFT (12 ft 7 in).
- Cargo capacity as a share of GVWR, 14.7%: eleventh-smallest of 123, between the 40LOFT (14.5%) and the 331BTS (16.5%).
- Grey tank, 65 gal: shared with the 40LOFT and JAYLOFT; of 118, 97 smaller and eighteen larger, nearest the 130RDW, 172DBW and seventeen others (40 gal) and the 333BTS, 334RTS and two others (71.5 gal).
- Cargo capacity, 2,060 lb: 28th-largest of 123, between the 21QB (2,045 lb) and the 380DQS and 40DLFT (2,070 lb).
- Sleeping capacity, 10: shared with the 250BH, 250BHW and seventeen others; of 110, 84 smaller and six larger, nearest the 264BH, 264BHW and three others (9) and the 321BDS, 324BDS and two others (11).
- Interior height, 6 ft 7 in: 32nd-lowest of 123, between the 130BH, 130BHW and 28 others (6 ft 6 in) and the 40LOFT (6 ft 8 in).
- Fresh tank, 52 gal: shared with the 200MKS, 210QB and 47 others; of 123, 31 smaller and 42 larger, nearest the 40LOFT (51 gal) and the 40FKDS (53 gal).
Next to the 40LOFT (2021–2025 page), the nearest lighter floorplan by dry weight, the 40LSDL is 15 lb heavier by dry weight, has a GVWR 50 lb higher, has 35 lb more cargo capacity, is 1 ft 1 in longer, stands 3 in lower, has 1 in less interior height, has a fresh tank 1 gal larger and sleeps two more; the two publish the same grey tank and black tank.
Next to the JAYLOFT (2025–2026 page), the nearest heavier floorplan by dry weight, the 40LSDL is 420 lb lighter by dry weight, has a GVWR 300 lb lower, has 120 lb more cargo capacity, stands 7 in lower, has 2 ft 3 in less interior height and sleeps one more; the two publish the same length, fresh tank, grey tank and black tank.
Specifications by model year
2024 is the only model year this catalogue holds a verified factory record for the 40LSDL. That record is published here on its own, and it is not a general specification for the floorplan: Jayco revises published weights, ratings and even tire sizes from one model year to the next, so every figure below is evidence about 2024 and about no other year.
| Model year | Dry (UVW) | GVWR | Cargo (CCC) | Dry tongue | Sleeps | Tire size |
|---|---|---|---|---|---|---|
| 2024 | 11,940 | 14,000 | 2,060 | 10,105 | 10 | ST235/80R16'E' |
The row above is the 2024 model year’s own record from Jayco’s model page for that year. When a second model year is sourced for this floorplan, it joins the table above on this same page and at this same address — nothing moves and no link breaks. The figures in the tow-critical placard at the top of this page are that same 2024 record. On the weights, overall length and tire size, that record and Jayco’s own 2024 model page agree on every field both of them publish. Exterior height is not compared: Jayco publishes a bare height, a with-A/C height and a with-2nd-A/C height, and the single height row carried here cannot be matched to one of them, so no claim is made either way.
02 Full 2024 specifications
Published figure flagged, printed not corrected. Jayco's own model page prints a dry tongue weight of 10,105 lb for the 2024 model year of this floorplan, against a published dry weight of 11,940 lb. That puts 85% of the trailer’s dry weight on the hitch. Across the 1,738 other travel-trailer records on this site that publish both figures, the median is 12%. We re-read the source and 10,105 lb is the figure it prints. This site does not guess what the figure should have been. It is shown as published, listed on the published-figure conflicts page, and left out of the tongue-weight ranges and medians on the tow-match and state-of-market pages and out of the tow matcher’s payload check. Anything on this page worked out from it, such as its share of dry weight or the payload it takes, carries the same problem. Weigh the actual tongue before sizing a hitch or a tow vehicle’s payload.

How these published figures sit against the rest of the catalogue: travel trailer tongue weight by size; fresh, grey and black tank sizes; camper trailer size chart.
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).

04 Buying a 2024 40LSDL at 2 model years old
Tyres are the first thing to age out
RV tyres are usually replaced on age rather than tread, at roughly five to seven years from the DOT date code on the sidewall. On a 2-year-old trailer the originals (ST235/80R16'E') may still be fitted — read the four-digit date code, not the tread.
Roof and seam sealant is on a service interval
Travel trailers rely on sealant at every roof penetration, along the front cap and around every window and marker light. Inspection is typically annual and re-sealing every few years; ask for the service records rather than assuming.
Weigh it before you tow it
Every weight on this page is a DRY factory figure for the 2024 model year. A used trailer carries its previous owner's additions, and a travel trailer puts its tongue load on the tow vehicle's hitch and through its rear axle. Weigh the loaded rig at a public scale and check it against the tow vehicle's payload, rear-axle and hitch ratings.
05 How it compares
Every Jay Flight Bungalow floorplan this catalogue holds a verified factory record for, with its own published weights.
06 Loading it for a trip
A full 52-gallon fresh tank is about 432 lb of water (water counts as cargo: 49 CFR 571.120 S10.4.2), 21% of the 40LSDL’s 2,060 lb cargo capacity, leaving 1,628 lb (163 lb per rated berth). Across 123 Jay Flight floorplans the water share runs 13% to 47%, and 103 give up more than this one. Nearest on that share: Jay Flight 40LOFT at 21% and Jay Flight 178DBSW at 21%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.120 S10.4.3).
07 Where this floorplan sits
