2027 Forest River Westbrook21MLXC

The Westbrook 21MLXC has 2,347 lbs of cargo capacity between 5,318 lbs dry and its 7,665 lbs GVWR, 31% of that rating; filling its 42-gallon fresh tank at 8.3 lb a gallon uses 349 lbs of it (how to read trailer weights).

Forest River’s 2027 floorplan drawing for the 21MLXC shows, at the front, a camp king bed between wardrobes with overhead cabinets. Mid-coach: an air fryer, a fridge and a jackknife sofa in a slide (theater seating is an option), a dinette with an entertainment center, and a pantry with shelves. At the rear: a kitchen along the rear with a sink and overhead cabinets, and a bath with a shower, a medicine cabinet and linen storage. It draws one slide-out and a 15-foot awning. Outside it labels drop-frame super pass-through storage. Layouts change with options; check the unit itself.

Tongue weight is 665 lbs, 13% of the dry weight as published; it rises as the trailer is loaded and counts against the tow vehicle’s tongue-weight and payload limits (tongue weight by size).

Off hookups: 68 gallons of grey and black capacity against 42 gallons of fresh water, so fresh water runs out first (tank sizes by length).

Against the rest of the Westbrook roster this is the 5th of 8 floorplans by dry weight, in a line that runs from 3,149 lbs to 7,343 lbs. It sits in the middle of the line by weight.

Plan the tow on loaded weight, not the 5,318 lbs dry figure: half the published cargo capacity brings this plan to about 6,492 lbs, and the published GVWR of 7,665 lbs is the limit (how to read trailer weights).

Forest River’s line listing and this floorplan’s own factory page agree on all 4 shared figures. Dry weight plus cargo capacity equals the published GVWR exactly. A missing row means Forest River does not publish that figure (how figures are verified).

Forest River publishes no written floorplan description for this plan; the layout described above is read off Forest River’s own floorplan drawing for this model year. 21MLXC is a Westbrook designation, and this site does not decode the code itself into a layout claim.

How the 21MLXC differs from the other seven Westbrook floorplans. Most distinctive first. How these ranks are worked out.

• GVWR, 7,665 lb: third-highest of eight, between the 26RBXC (7,620 lb) and the 27CC (7,805 lb).
• Cargo capacity, 2,347 lb: third-largest of eight, between the 26RBXC (1,757 lb) and the 27REXC (2,517 lb).
• Tongue weight, 665 lb: third-heaviest of eight, between the 26RBXC (620 lb) and the 27CC (805 lb).
• Tongue weight as a share of dry weight, 12.5%: third-smallest of eight, between the 26RBXC (10.6%) and the 27CC (12.6%).
• Dry weight, 5,318 lb: fourth-heaviest of eight, between the 25BHCC (4,853 lb) and the 26RBXC (5,863 lb).
• Cargo capacity as a share of GVWR, 30.6%: fourth-largest of eight, between the 27REXC (25.5%) and the 16RBCC (31.2%).
• Length, 25 ft 10 in: fourth-shortest of eight, between the 18BHCC (23 ft 3 in) and the 25BHCC (28 ft 8 in).
• Exterior height, 10 ft 8 in: shared with the 25BHCC, 26RBXC and 27CC; of eight, three lower and one taller, nearest the 16CC, 16RBCC and 18BHCC (10 ft 4 in) and the 27REXC (11 ft 1 in).
• Grey tank, 34 gal: shared with the 25BHCC; of eight, three smaller and three larger, nearest the 16CC, 16RBCC and 18BHCC (30 gal) and the 26RBXC (66 gal).

Next to the 25BHCC, the nearest lighter floorplan by dry weight, the 21MLXC is 465 lb heavier by dry weight, has a GVWR 175 lb higher, has 290 lb less cargo capacity, has a tongue weight 175 lb heavier and is 2 ft 10 in shorter; the two publish the same exterior height, fresh tank, grey tank and black tank.

Next to the 26RBXC, the nearest heavier floorplan by dry weight, the 21MLXC is 545 lb lighter by dry weight, has a GVWR 45 lb higher, has 590 lb more cargo capacity, has a tongue weight 45 lb heavier, is 3 ft 1 in shorter and has a grey tank 32 gal smaller; the two publish the same exterior height, fresh tank and black tank.

Westbrook is one of the few lines on this site where every published floorplan clears the bar for a full profile: eight plans, no dealer-stock-only entries, and dry weight plus cargo capacity equal to the published GVWR on all eight. The roster splits into single-axle and tandem-axle groupings and runs 3,149 to 7,343 lb dry on lengths of 20 feet 4 inches to 34 feet, with tongue weights of 415 to 1,060 lb.

A full 42-gallon fresh tank is about 349 lb of water (water counts as cargo: 49 CFR 571.110 S9.3.2), 15% of the 21MLXC’s 2,347 lb cargo capacity, leaving 1,998 lb. Across 8 Westbrook floorplans the water share runs 13% to 35%, and 5 give up more than this one. Nearest on that share: Westbrook 27REXC at 14% and Westbrook 26RBXC at 20%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.110 S9.3.3).
