01 What makes the 2026 40RLTS different
The Jay Flight Bungalow 40RLTS 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 2026 40RLTS, 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 14' 0" with the slide-outs run out for the 2026 model year, which is the measurement that matters for a site pitch as well as for the road.
For the 2026 model year Jayco published a 13,500-pound GVWR on a 11,560-pound dry weight, 1,940 pounds of published cargo capacity, a 1,630-pound dry tongue weight. That dry tongue is 14% of the dry weight, inside the 10–15% band conventionally quoted for a bumper-pull trailer. Tongue weight is not fixed — it moves with how the trailer is loaded, and weight added ahead of the axles raises it. A tongue load in that range wants a weight-distribution hitch, and the tow vehicle's tongue-weight limit is a separate number from its trailer-weight limit — check the loaded tongue against the hitch receiver's rating and the vehicle's payload, not against the tow rating alone. The 2026 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.
Against the 2025 build of the same floorplan, 5 published fields moved. The full comparison is in section 02, and it is drawn from two separate verified factory records rather than from one record and an assumption about the other.
A 2026 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.
Specifications by model year
This floorplan has a verified factory record for 5 model years here, 2021 to 2026, and the specification does not hold still. Across those years GVWR ranges from 13,000 lb in 2021 to 13,500 lb in 2026, a spread of 500 lb; dry weight ranges from 10,555 lb in 2023 to 11,560 lb in 2026, a spread of 1,005 lb; dry tongue weight ranges from 1,495 lb in 2021 to 1,630 lb in 2026, a spread of 135 lb. Even the published sleeping capacity moves (4 and 6). That is why each model year has its own page below, carrying only its own published figures. Nothing on a year page is copied across from a neighbouring year.
| Model year | Dry (UVW) | GVWR | Cargo (CCC) | Dry tongue | Sleeps | Tire size |
|---|---|---|---|---|---|---|
| 2021 | 11,175 | 13,000 | 1,825 | 1,495 | 4 | Not published |
| 2023 | 10,555 | 13,000 | 2,445 | 1,575 | 4 | Not published |
| 2024 | 10,825 | 13,000 | 2,175 | 1,510 | 6 | ST235/80R16'E' |
| 2025 | 11,155 | 13,300 | 2,145 | 1,515 | 4 | ST235/80R16'E' |
| 2026 | 11,560 | 13,500 | 1,940 | 1,630 | 4 | ST235/80R16'E' |
Every row is that model year’s own record from Jayco’s model page for that year. The figures in the tow-critical placard at the top of this page are the 2026 record from the source this catalogue originally profiled. On the weights, overall length and tire size, that record and Jayco’s own 2026 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.

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 2026 model year
Jayco changed 5 of the published fields between the 2025 and 2026 40RLTS. Every figure in both columns is that model year's own factory record — nothing here is carried across from the other year.
| Field | 2025 | 2026 | Change |
|---|---|---|---|
| Dry weight (UVW) | 11,155 | 11,560 | +405 lb |
| GVWR | 13,300 | 13,500 | +200 lb |
| Cargo capacity (CCC) | 2,145 | 1,940 | -205 lb |
| Dry tongue weight | 1,515 | 1,630 | +115 lb |
| Exterior height | 12' 2" | 12' 1" | — |
| Model year | Dry (UVW) | GVWR | Dry tongue | Sleeps | Tire size |
|---|---|---|---|---|---|
| 2023 | 10,555 | 13,000 | 1,575 | 4 | Not published |
| 2024 | 10,825 | 13,000 | 1,510 | 6 | ST235/80R16'E' |
| 2025 | 11,155 | 13,300 | 1,515 | 4 | ST235/80R16'E' |
| 2026 | 11,560 | 13,500 | 1,630 | 4 | ST235/80R16'E' |
Every row is that model year's own factory record, and each year links to its own page. The fuller table at the top of this page adds cargo capacity and names any model year that is deliberately not published here.
GVWR changed for 2026
GVWR was 13,300 for 2025 and is 13,500 for 2026 (+200 lb). Both figures are the manufacturer's own for their year.
Dry tongue weight changed for 2026
Dry tongue weight was 1,515 for 2025 and is 1,630 for 2026 (+115 lb). Both figures are the manufacturer's own for their year.
Where these numbers come from
Every figure on this page is read from Jayco's own 2026 model page for the 40RLTS — one source, one model year, no blending. The all-years parent page sets this year beside every other model year we hold, and where the record this catalogue originally profiled disagrees with Jayco's own model page, both figures are published there and neither is adjusted.
Fields Jayco does not publish for 2026
For this model year the factory record omits: Propane Unit (lbs) (Optional), Furnace, Auto-ignition (BTU output). Those rows read “Not published” on this page. They are deliberately not filled in from an adjacent model year — a neighbouring year's figure is an inference about this one, not a measurement of it.
04 Buying a 2026 40RLTS today
Still in warranty
A current-model-year trailer is normally inside Jayco's structural and component warranties. Get the delivery PDI paperwork and confirm the warranty start date is the date of sale, not the date of build.
Check the build date, not the model year
Model-year 2026 units can be built well before the calendar year turns. The federal certification label inside the entry door carries the real month of manufacture, and it is what the tyre date codes should be read against.
Weigh it before you tow it
Every weight on this page is a DRY factory figure for the 2026 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 — and to its other years
The same floorplan one model year earlier, with its own published weights.
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 434 lb of water (water counts as cargo: 49 CFR 571.120 S10.4.2), 22% of the 40RLTS’s 1,940 lb cargo capacity, leaving 1,506 lb (377 lb per rated berth). Across 117 Jay Flight floorplans the water share runs 13% to 47%, and 84 give up more than this one. Nearest on that share: Jay Flight JAYLOFT at 22% and Jay Flight 265MWS at 22%. 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
Closest sibling: the Jay Flight 401FLTS, nearest on the published figures. It differs on 5 of the 9 fields both publish (this plan first): dry weight 11,560 lb vs 10,355 lb; GVWR 13,500 lb vs 12,000 lb; cargo capacity 1,940 lb vs 1,645 lb; dry hitch weight 1,630 lb vs 1,515 lb; grey tank 32 gal vs 39 gal. They match on length, sleeps, fresh tank and black tank.

11 NHTSA safety record
NHTSA holds 25 recall campaigns and 80 owner complaints against the Jay Flight line. They are counted separately: a recall is a confirmed defect with a remedy, a complaint one owner’s unverified account.
What to look at on a used one. Across the 80 complaints filed on this line the most-reported components are equipment (42%), unknown or other (12%) and structure (11%).
Recall coverage here is not complete, and complaints are owners’ unverified reports (how this record is built). Check a specific VIN at NHTSA before you buy. Full tables are on the Jay Flight line page.
