Jayco Jay Feather · 2025–202628RB

The Jay Feather 28RB is one of Jayco's Jay Feather travel trailers, the lightweight step-up line positioned above the value Jay Flight SLX and below the premium Eagle HT. This page covers one model year of it — the 2026 28RB, 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' 0" wide closed and 11' 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 8,400-pound GVWR on a 6,510-pound dry weight, 1,890 pounds of published cargo capacity, a 745-pound dry tongue weight. That dry tongue is 11% 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 ST225/75R15'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 28RB differs from the other 46 Jay Feather floorplans. Most distinctive first. Sibling pages may cover other model years than this one (2025–2026). How these ranks are worked out.

• Cargo capacity, 1,890 lb: fifth-largest of 47, between the 30RKB (1,730 lb) and the 32RL (1,900 lb).
• Grey tank, 76 gal: shared with the 23MBD, 24FK and two others; of 47, 41 smaller and one larger, nearest the 27MK and 32RL (71 gal) and the 26FK (91.5 gal).
• Exterior height, 10 ft 3 in: shared with the 30RKB and 32RL; of 47, 40 lower and four taller, nearest the 23MBD, 25RB and five others (10 ft 2 in) and the 29BHB (10 ft 4 in).
• GVWR, 8,400 lb: twelfth-highest of 47, between the 27BH and 27RK (8,200 lb) and the 29BHB and 30QB (8,500 lb).
• Dry weight, 6,510 lb: thirteenth-heaviest of 47, between the 27BH (6,490 lb) and the 27RK (6,655 lb).
• Dry tongue weight, 745 lb: thirteenth-heaviest of 47, between the 25RB (715 lb) and the 29QBH (750 lb).
• Length, 33 ft 1 in: thirteenth-longest of 47, between the 27RK (32 ft 4 in) and the 27BHB and 27MK (33 ft 2 in).
• Cargo capacity as a share of GVWR, 22.5%: sixteenth-largest of 47, between the 18FBS (22.3%) and the 26BHSL (22.8%).
• Black tank, 38 gal: shared with the 16DB, 16FBS and ten others; of 47, 31 smaller and three larger, nearest the 22RB (34 gal) and the 23MBD and 29RL (40 gal).
• Sleeping capacity, 4: shared with the 15MRB, 166FBS and eleven others; of 47, eight smaller and 25 larger, nearest the 173MRB, 183FBS and three others (3) and the 171BH (5).
• Dry tongue weight as a share of dry weight, 11.4%: shared with the 19MRK, 22RB and 27BHB; of 47, nineteen smaller and 24 larger, nearest the 16FBS and 18FBS (11.3%) and the 16RB and 23RK (11.5%).

Next to the 27BH (2026–2027 page), the nearest lighter floorplan by dry weight, the 28RB is 20 lb heavier by dry weight, has a GVWR 200 lb higher, has 180 lb more cargo capacity, has a dry tongue weight 95 lb lighter, is 10 in longer, stands 1 in taller and sleeps four fewer; the two publish the same interior height, fresh tank, grey tank and black tank.

Next to the 27RK (2025 page), the nearest heavier floorplan by dry weight, the 28RB is 145 lb lighter by dry weight, has a GVWR 200 lb higher, has 345 lb more cargo capacity, has a dry tongue weight 145 lb lighter, is 9 in longer, stands 2 in lower, has a grey tank 16 gal larger, has a black tank 8 gal larger and sleeps two fewer; the two publish the same interior height and fresh tank.

This floorplan has a published factory record for 2 model years here, 2025 to 2026. The specification does not hold still: dry weight runs from 6,510 lb (2026) to 6,770 lb (2025); dry tongue weight runs from 745 lb (2026) to 815 lb (2025). The published sleeping capacity changes across the years: up to 6 in 2025, up to 4 in 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 28RB. Every figure in both columns is that model year's own factory record — nothing here is carried across from the other year.

A full 55-gallon fresh tank is about 457 lb of water (water counts as cargo: 49 CFR 571.110 S9.3.2), 24% of the 28RB’s 1,890 lb cargo capacity, leaving 1,434 lb (358 lb per rated berth). Across 47 Jay Feather floorplans the water share runs 23% to 43%, and 42 give up more than this one. Nearest on that share: Jay Feather 32RL at 24% and Jay Feather 15TBSL at 25%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.110 S9.3.3).
