2921RL published figures, first
2921RL: the rear wall is the entertainment wall
Forest River's drawing puts a TV and fireplace across the rear wall and turns two slides toward each other in front of it. The off-door slide carries a 60-inch hide-a-bed, overhead cabinets, and the microwave and cooktop; the door-side slide carries a second 60-inch hide-a-bed with overhead cabinets. Forward of them, a 60-inch theater seat stands in the middle of the floor facing the rear, backed by a table with bar stools. The fridge and a kitchen counter with sink and overhead cabinets sit on the off-door side.
Beyond that come a mid bath with shower, toilet, and linen cabinet, then a front bedroom with a 60 by 80 inch queen, a wardrobe, a second wardrobe with washer and dryer prep, and pass-through storage at both front corners. A single Solid Step entry opens under a 19 ft awning, and the drawing carries the Power Package badge.
Of the two 35 ft 4 in plans, this is the one that turns the rear into a room for watching: seating faces the rear wall from both slides and from the theater seat in the middle. The 2916RL puts a hide-a-bed on that wall instead and moves the TV and fireplace beside its kitchen slide.
RVUSA counts sleeping for 6, second only to the 2706BH, and two slides. At 8,143 lb dry the 2921RL is 10 of 11 by weight, and its GVWR of 9,963 lb is the highest of the nine on record. Yet its hitch weight is 820 lb, 5 of 11, and that is 10.1% of dry weight, the lowest share of any Ultra Lite. Cargo carrying capacity is 1,820 lb, 7 of 11, the same as its GVWR margin (6 of 9). Tanks total 144 gal, with a 45 gal gray tank on a trailer that sleeps 6.
Forest River's 2027 Rockwood Ultra Lite 2921RL page and drawing →Four steps through a 2921RL
- Open both rear slides and fold out both 60-inch hide-a-beds at once. They face each other, so check the floor left between them with both beds made.
- Sit on the freestanding 60-inch theater seat and check its view to the rear-wall TV with the hide-a-beds open.
- Stand at the bar-stool table and at the counter by the fridge. The microwave and cooktop are in the off-door slide rather than on this counter, so cooking and prep happen in two places.
- In the front bedroom, open the wardrobe with washer and dryer prep. Installed appliances there count against the 1,820 lb cargo capacity and add weight at the hitch end.

Length, dry weight, hitch weight, cargo capacity, tanks, the awning, and the room layout come from Forest River's 2027 Rockwood Ultra Lite 2921RL page and drawing, read on 2026-09-26. Forest River labels UVW and CCC as estimated averages based on standard build optional equipment, so the label on the unit takes precedence. GVWR, sleeping capacity, and slide count come from RVUSA's 2027 spec guide.
