Jayco Jay Flight Bungalow · 2025–2026JAYLOFT

The Jay Flight Bungalow JAYLOFT 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 JAYLOFT, 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' 7" 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 14,300-pound GVWR on a 12,360-pound dry weight, 1,940 pounds of published cargo capacity, a 1,775-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, 8 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.

How the JAYLOFT differs from the other 122 Jay Flight floorplans. Most distinctive first. Sibling pages may cover other model years than this one (2025–2026). How these ranks are worked out.

• Dry weight, 12,360 lb: second-heaviest of 123, between the 40LSDL (11,940 lb) and the 40DLFT (12,430 lb).
• GVWR, 14,300 lb: second-highest of 123, between the 40LSDL (14,000 lb) and the 40DLFT (14,500 lb).
• Dry tongue weight, 1,775 lb: second-heaviest of 122, between the 40RLTS (1,630 lb) and the 402RLTS (1,830 lb).
• Exterior height, 12 ft 11 in: tallest of 109, level with the 40DLFT; next are the 401LOFT, 402DLFT and 404LOFT (12 ft 10 in).
• Cargo capacity as a share of GVWR, 13.6%: shared with the 401LOFT and 404LOFT; of 123, one smaller and 119 larger, nearest the 402DLFT (13.1%) and the 401FLTS (13.7%).
• Length, 41 ft 11 in: shared with the 40LSDL; of 123, 119 shorter and two longer, nearest the 402DLFT and 40DLFT (41 ft 6 in) and the 401LOFT and 404LOFT (42 ft).
• Interior height, 8 ft 10 in: shared with the 401LOFT and 40DLFT; of 123, 118 lower and two taller, nearest the 255THW (8 ft 5 in) and the 402DLFT and 404LOFT (8 ft 11 in).
• Dry tongue weight as a share of dry weight, 14.4%: eleventh-largest of 122, between the 331BTS (14.2%) and the 401FLTS (14.6%).
• Grey tank, 65 gal: shared with the 40LOFT and 40LSDL; 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).
• Sleeping capacity, 9: shared with the 264BH, 264BHW and two others; of 110, 79 smaller and 26 larger, nearest the 178DBS, 178DBSW and eighteen others (8) and the 250BH, 250BHW and eighteen others (10).
• Cargo capacity, 1,940 lb: shared with the 40RLTS; of 123, 82 smaller and 39 larger, nearest the 265MWS (1,930 lb) and the 334RTS (1,945 lb).
• 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 40LSDL (2024 page), the nearest lighter floorplan by dry weight, the JAYLOFT is 420 lb heavier by dry weight, has a GVWR 300 lb higher, has 120 lb less cargo capacity, stands 7 in taller, has 2 ft 3 in more interior height and sleeps one fewer; the two publish the same length, fresh tank, grey tank and black tank.

Next to the 40DLFT (2023–2026 page), the nearest heavier floorplan by dry weight, the JAYLOFT is 70 lb lighter by dry weight, has a GVWR 200 lb lower, has 130 lb less cargo capacity, has a dry tongue weight 225 lb heavier, is 5 in longer, has a grey tank 32.5 gal larger and sleeps two more; the two publish the same exterior height, interior height, fresh tank and black tank.

This floorplan has a published factory record for 2 model years here, 2025 to 2026. The specification does not hold still: GVWR runs from 14,000 lb (2025) to 14,300 lb (2026); dry weight runs from 12,015 lb (2025) to 12,360 lb (2026); dry tongue weight runs from 1,715 lb (2025) to 1,775 lb (2026). Each year’s complete record is printed separately below, carrying only that year’s own published figures and source. Nothing is copied across from a neighbouring year.

Jayco changed 8 of the published fields between the 2025 and 2026 JAYLOFT. Every figure in both columns is that model year's own factory record — nothing here is carried across from the other year.

A full 52-gallon fresh tank is about 432 lb of water (water counts as cargo: 49 CFR 571.120 S10.4.2), 22% of the JAYLOFT’s 1,940 lb cargo capacity, leaving 1,508 lb (168 lb per rated berth). Across 123 Jay Flight floorplans the water share runs 13% to 47%, and 92 give up more than this one. Nearest on that share: Jay Flight 255THW at 22% and Jay Flight 40RLTS at 22%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.120 S10.4.3).
