Jayco Jay Feather · 2024–202621MBH

The Jay Feather 21MBH 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 21MBH, 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 10' 11" 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 6,995-pound GVWR on a 5,450-pound dry weight, 1,545 pounds of published cargo capacity, a 600-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 ST205/75R14'D' 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.

How the 21MBH differs from the other 46 Jay Feather floorplans. Most distinctive first. Sibling pages may cover other model years than this one (2024–2026). How these ranks are worked out.

• Dry tongue weight as a share of dry weight, 11%: shared with the 22BH and 24BH; of 47, eleven smaller and 33 larger, nearest the 23MBD (10.9%) and the 25BH (11.1%).
• Grey tank, 30.5 gal: shared with the 18FBS, 21MML and 26RL; of 47, ten smaller and 33 larger, nearest the 166FBS, 171BH and five others (30 gal) and the 15MRB, 16DB and eight others (38 gal).
• Dry tongue weight, 600 lb: eighteenth-lightest of 47, between the 18MBH (595 lb) and the 22BH (610 lb).
• Length, 26 ft 8 in: twentieth-shortest of 47, between the 21MML (25 ft 5 in) and the 24FK (27 ft).
• Dry weight, 5,450 lb: 21st-lightest of 47, between the 25RLSL (5,310 lb) and the 26BHSL (5,555 lb).
• GVWR, 6,995 lb: 21st-lowest of 47, between the 25RLSL (6,800 lb) and the 22RB and 24RL (7,000 lb).
• Cargo capacity as a share of GVWR, 22.1%: shared with the 17RBSL; of 47, 28 smaller and seventeen larger, nearest the 26RL (22%) and the 18FBS (22.3%).
• Cargo capacity, 1,545 lb: shared with the 18RBF and 27RK; of 47, 25 smaller and nineteen larger, nearest the 29RL (1,520 lb) and the 19MRK (1,580 lb).
• Exterior height, 9 ft 11 in: shared with the 166FBS, 16FBS and four others; of 47, seventeen lower and 23 taller, nearest the 171BH, 183FBS and five others (9 ft 10 in) and the 18MBH, 18RBF and 22BH (10 ft).
• Sleeping capacity, 6: shared with the 17BHSL, 24RL and five others; of 47, 23 smaller and sixteen larger, nearest the 171BH (5) and the 22BH and 23MBD (7).
• Black tank, 30.5 gal: shared with the 15MRB, 16RB and fifteen others; of 47, eleven smaller and eighteen larger, nearest the 15TBSL, 166FBS and eight others (30 gal) and the 30QB (31 gal).

Next to the 25RLSL (2026–2027 page), the nearest lighter floorplan by dry weight, the 21MBH is 140 lb heavier by dry weight, has a GVWR 195 lb higher, has 55 lb more cargo capacity, has a dry tongue weight 40 lb heavier, is 3 ft 5 in shorter, has a grey tank 7.5 gal smaller and has a black tank 7.5 gal smaller; the two publish the same exterior height, interior height, fresh tank and sleeping capacity.

Next to the 26BHSL (2026–2027 page), the nearest heavier floorplan by dry weight, the 21MBH is 105 lb lighter by dry weight, has a GVWR 205 lb lower, has 100 lb less cargo capacity, has a dry tongue weight 80 lb lighter, is 3 ft 9 in shorter, stands 1 in taller, has a grey tank 7.5 gal smaller, has a black tank 7.5 gal smaller and sleeps four fewer; the two publish the same interior height and fresh tank.

This floorplan has a published factory record for 3 model years here, 2024 to 2026. The specification does not hold still: dry weight runs from 5,450 lb (2026) to 5,545 lb (2025); dry tongue weight runs from 587 lb (2024) to 615 lb (2025). The published sleeping capacity changes across the years: up to 8 in 2024–2025, up to 6 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 5 of the published fields between the 2025 and 2026 21MBH. 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), 30% of the 21MBH’s 1,545 lb cargo capacity, leaving 1,088 lb (181 lb per rated berth). Across 47 Jay Feather floorplans the water share runs 23% to 43%, and 23 give up more than this one. Nearest on that share: Jay Feather 18RBF at 30% and Jay Feather 17RBSL at 30%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.110 S9.3.3).
