01 What makes it unique
The Rockwood Ultra Lite 2912BS leaves Forest River's factory at 7,854 lbs dry with 1,898 lbs of cargo capacity. Forest River publishes no GVWR for this line, so the loaded rating is not quoted on this page and is not computed from the other two figures. What the cargo number covers is defined by the factory: fresh water, gear, food, batteries and every dealer-installed accessory come out of it. Fresh water is 8.3 lb per gallon, so filling the 54-gallon fresh tank spends 448 lbs of the 1,898 lbs before anything else goes in.
Dry tongue weight is 952 lbs, or 12% of the dry weight. Ten to fifteen percent is the conventional band for a bumper-pull trailer, and this plan sits inside it as published. Tongue weight is not fixed: it moves with how the trailer is loaded, and weight added ahead of the axles raises it. A weight-distribution hitch is the normal fitment at this tongue load, and the tow vehicle's tongue-weight limit is a separate number from its trailer-weight limit.
Tank capacities are 54 gallons fresh, 90 grey and 45 black, 135 gallons of waste capacity against 54 gallons of supply. The ratio is what governs how long the trailer can sit off hookups: waste capacity exceeds fresh, so the fresh tank is the binding constraint and refilling extends the stay. Forest River publishes these three figures per floorplan, and they are the factory's numbers rather than a segment average.
Against the rest of the Rockwood Ultra Lite roster this is the 7th of 9 floorplans by dry weight, in a line that runs from 6,158 lbs to 8,559 lbs. It sits in the heavier third of the line. Comparing floorplans inside one line is more reliable than comparing across brands, because every figure here comes from the same factory channel on the same day.
A useful way to read these figures is to stop planning against the dry weight. Nobody tows a trailer at 7,854 lbs: that is the weight before water, batteries, propane, bedding, food, tools and anything the dealer bolted on. Load half the published cargo capacity and this plan is already near 8,803 lbs on the road. Because Forest River publishes no loaded rating for this line, the ceiling has to come from the trailer's own weight label rather than from this page, and the comparison you make against the tow vehicle should use the loaded figure.
Every number above was read from one factory document: Forest River's own 2022 brochure for this line, and each figure was read back against that document's text before it was published. This is a single-channel record rather than the two-page cross-check this site runs on saved factory web pages, and it is described that way rather than dressed up as more. The brochure publishes no GVWR for this line, so the loaded rating is shown as not published and is never computed from dry weight plus cargo capacity. Where a figure is missing from this page it is because the brochure does not publish it, not because it was hard to find - and the row says so rather than being quietly dropped.
Forest River publishes no floorplan description for this plan in the channel this page is built from - only the numeric specification block. Rather than describe a layout from the floorplan code, which would be a guess dressed as a fact, this page carries what the factory publishes and says where it stops. 2912BS is a Rockwood Ultra Lite designation and this site does not decode it into a layout claim.

03 The Rockwood Ultra Lite floorplan family
Ultra Lite is where the Rockwood range stops being a mid-size-SUV proposition. Dry weight runs 6,614 to 8,559 lb across the seven plans profiled here and dry tongue weight runs 796 to 1,100 lb, which is enough hitch load that weight distribution stops being optional and the tow vehicle's own payload starts to matter. Cargo capacity runs 1,341 to 2,233 lb, and the heaviest trailer on the roster has the least of it - so the plan that looks like the most capable one on dry weight is the one with the least room to load. Fresh water is 54 gallons and black is 45 on every plan; grey is either 45 or 90 gallons. Lengths run 29 ft 9 in to 33 ft 1 in.

Ultra Lite is the larger of Rockwood's two main travel-trailer classes, sold under the Flagstaff badge as the Super Lite. The two use different floorplan codes throughout - 2613BS is the Super Lite 26RLBS; 2614BS is the Super Lite 26RKBS; 2706WS is the Super Lite 27BHWS; 2720IK is the Super Lite 27FBIK; 2906BS is the Super Lite 29RLBS; 2911BS is the Super Lite 29BHS; 2912BS is the Super Lite 29RBS. Each pair is one trailer, identical on every published field, and the mapping above is the only way to read a code from one badge against the other. Forest River publishes no GVWR for this line, so the loaded rating is shown as not published and is never computed from dry weight plus cargo capacity. These figures come from one factory document rather than from the two separate factory renderings this site cross-reads on Forest River's web channel, and every figure was read back against that document's own text before publication. Sleeping capacity, axle count, tire size and MSRP are not published in the brochure and are absent here rather than estimated.
04 Notes on this floorplan
What Forest River does not publish for this line
Sleeping capacity, axle count, tire size and MSRP are absent from Forest River's specification channel for Rockwood Ultra Lite, so they are absent here. They are not estimated from the segment, not carried over from a sibling floorplan, and not taken from a dealer listing quoting itself. A tire size in particular is a safety-relevant number that differs between two codes a digit apart, and this site does not guess one.
There is no factory GVWR for this trailer
Forest River publishes dry weight, cargo capacity and dry tongue weight for every Rockwood Ultra Lite floorplan and publishes no GVWR for any of them. The factory's own glossary defines cargo capacity as GVWR minus UVW, which means the rating can be worked out - and a figure you worked out is not a figure the manufacturer published, so this page does not print one. Use the weight label on the trailer itself, which every Forest River unit carries.
Awning size is not published for this floorplan
Forest River publishes an awning size for some Rockwood Ultra Lite floorplans and not for this one. The row reads as unpublished rather than being filled from a neighbouring plan in the same roster.
Weigh it before you tow it
Every figure on this page is a factory publication for a standard build. Forest River's own footnote on unloaded weight calls it an estimated average based on a standard build with optional equipment, and options, dealer-installed accessories and the previous owner's additions all move it. The only weight that governs your towing decision is the one under your own trailer on a scale, loaded the way you actually travel.
05 How it compares
7,605 lbs dry against this plan's 7,854 lbs, a difference of 249 lbs. Same line, same factory channel, same model year - so the gap is a real one rather than a difference in how two brands measure.
8,324 lbs dry, 470 lbs more than this plan, and 1,511 lbs of cargo capacity against this one's 1,898 lbs. Stepping up a floorplan usually buys length before it buys payload.
2,233 lbs of cargo capacity, the highest of the 7 Rockwood Ultra Lite floorplans profiled here. If payload rather than length is the binding constraint, that is the plan to compare against.
06 Loading it for a trip
A full 54-gallon fresh tank is about 450 lb of water, 24% of the 2912BS’s 1,898 lb cargo capacity, leaving 1,448 lb. Across 17 Rockwood Ultra Lite floorplans the water share runs 18% to 34%, and 7 give up more than this one. Nearest on that share: Rockwood Ultra Lite 2618RD at 23% and Rockwood Ultra Lite 2608BS at 25%.
07 Where this floorplan sits
Closest sibling: the Rockwood Ultra Lite 2902SW, nearest on the published figures. It differs on 4 of the 7 fields both publish (this plan first): length 35 ft 2 in vs 35 ft 3 in; dry weight 7,854 lb vs 7,610 lb; cargo capacity 1,898 lb vs 2,110 lb; dry hitch weight 952 lb vs 920 lb. They match on fresh tank, grey tank and black tank.

11 NHTSA safety record
NHTSA holds 35 recall campaigns and 209 owner complaints against the Rockwood & Flagstaff line. They are counted separately: a recall is a confirmed defect with a remedy, a complaint one owner’s unverified account.
What to look at on a used one. Across the 209 complaints filed on this line the most-reported components are tires (24%), structure (15%) and wheels (14%).
