2024 Keystone Outback328RL

The Outback 328RL is one of the 9 floorplans Keystone published for the 2024 model year of its Outback travel-trailer line — a line built from 2005 through 2026 and since dropped from the brand's directory, which makes the used fleet the only place to find one. At 37' 7" exterior length with 3 slide-outs, it is catalogued sleeping 6, and the factory equipped the 2024 line with a 10 cu ft refrigerator and Coleman-Mach Quiet Series 15K BTU Ducted Air Conditioner.

The weight record for this plan is unusually well attested for a discontinued trailer: RVUSA's structured MY2024 record publishes a dry weight of 8,791 pounds against a GVWR of 10,500, leaving 1,709 pounds of payload, on a 1,075-pound published hitch weight — and the factory's own 2024 brochure table prints the same dry, payload and hitch figures to the pound. Dry weight plus payload equals GVWR exactly. Tanks run 54 gallons fresh, 76 grey and 38 black, and height is 11' 4" with the air conditioner.

For tow planning, treat the 1,075-pound hitch figure as a dry floor: it is 12% of dry weight, and a loaded trailer pushes tongue load higher, so match the plan against your tow vehicle's payload and receiver ratings at GVWR (10,500 pounds), not at dry weight. Because the line is out of production, the governing numbers for any specific unit are the ones on its own federal weight sticker — the record here is the published base-unit figure for the model year, the right starting point for shortlisting and the wrong substitute for weighing the actual trailer.

Keystone built the Outback travel trailer from 2005 through the 2026 model year and then dropped it from the brand directory; the used fleet is what remains. MY2024 is the anchor year profiled on this site — the newest model year whose published record carries the complete weight set (dry weight, GVWR, payload and hitch weight, published by RVUSA's structured records and cross-checked against the factory's own 2024 brochure table). The 328RL on this page is highlighted; each other profiled plan links to its own page. The 2025 roster grew to fourteen plans and the final 2026 year ran ten with a smaller-floorplan refresh, but neither of those years has a published dry weight or GVWR in any verifiable source, so they are catalogued on the line hub rather than profiled.

A full 54-gallon fresh tank is about 450 lb of water (water counts as cargo: 49 CFR 571.120 S10.4.2), 26% of the 328RL’s 1,709 lb cargo capacity, leaving 1,259 lb (210 lb per rated berth). Across 8 Outback floorplans the water share runs 20% to 27%, and 1 gives up more than this one. Nearest on that share: Outback 332ML at 24% and Outback 330RL at 27%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.120 S10.4.3).

Closest sibling: the Outback 332ML, nearest on the published figures. It differs on 4 of the 9 fields both publish (this plan first): length 37 ft 7 in vs 37 ft 10 in; dry weight 8,791 lb vs 8,653 lb; cargo capacity 1,709 lb vs 1,847 lb; dry hitch weight 1,075 lb vs 1,020 lb. They match on sleeps, GVWR, fresh tank, grey tank and black tank.

Either side of it by GVWR: Outback 330RL matches it at 10,500 lb GVWR.

All 8 Outback floorplans: Outback line hub.

Against the 328RL: the Coachmen Freedom Express Ultra Lite 320BHDS sleeps 2 more; the Jay Flight 333BTS sleeps 5 more; the Seismic 265 is 6 ft shorter.

16 of the 18 fields this catalogue tracks are published for the 328RL. Not published: exterior height, interior height, tire size (a description is published, a size is not).

Sourcing rules: methodology.
