2022 Forest River Rockwood Ultra Lite / Flagstaff Super Lite2911BS

The Rockwood Ultra Lite 2911BS leaves Forest River's factory at 7,605 lbs dry with 2,233 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 2,233 lbs before anything else goes in.

Dry tongue weight is 1,038 lbs, or 14% 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, 45 grey and 45 black, 90 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 6th 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 7,605 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 8,721 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-rendering cross-check this site runs on factory web captures, 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. 2911BS is a Rockwood Ultra Lite designation and this site does not decode it into a layout claim.

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.

This floorplan carries its water comfortably. A full 54-gallon fresh tank is roughly 20% of the 2,233-pound cargo capacity, leaving the 2911BS with a usable gear budget even when you tow full.

The published dry tongue weight of 1,038 pounds is 14% of the 7,605-pound dry weight, which sits inside the 10–15% band usually quoted for stable towing. It is still a dry figure: loading the front pass-through and the fresh tank both push it up.

Tank balance is generous here: 54 gallons of fresh against 45 grey and 45 black, so waste capacity keeps pace with supply and the fresh tank is the constraint that ends a dry stay.

Ranked by dry weight, the 2911BS sits 10 of 17 in the Rockwood Ultra Lite line: 7,605 pounds against a line that runs from 6,048 to 8,559 pounds. That position is the useful thing to know, because the plans immediately either side of it are the real alternatives.

Either side of it in the same line: Rockwood Ultra Lite 2706WS is 295 pounds lighter at 7,310 lb dry; and Rockwood Ultra Lite 2911SB matches it exactly at 7,605 lb dry.

1 other Rockwood Ultra Lite plan shares this floorplan’s 7,605 lb dry, so the ranking above separates plans that tow to the same ceiling. On a shared chassis the figure that actually differs between them is cargo capacity and where the weight sits, not the rating.

Against the 2911BS: the Eagle 264BHOK is 5 lb heavier and 3 ft shorter; the Jay Flight SLX 324BDS is 10 lb heavier; the Campsite Reserve 32GT is 12 lb lighter and 4 ft longer. Those are differences in the published numbers only — what they cost, how they are built and how they live are separate questions each of those pages answers on its own terms.

Those are the nearest travel trailers from other lines by weight — one per line, picked by proximity on that figure and nothing else. They are listed so the same tow vehicle can be checked against real alternatives, not because they are equivalent inside; layout, build and price diverge sharply across that group.

For scale, the Rockwood Ultra Lite floorplans profiled here run 6,048 to 8,559 pounds dry and 30 to 35 feet of exterior length across 17 plans. Where a floorplan falls in that spread usually says more about which vehicle can tow it, and which site it fits, than the layout name does.

This catalog tracks 18 specification fields per floorplan. Named sources publish 9 of them for the 2911BS. The rest are not shown, because the alternative is reading a figure across from a sibling floorplan or from what the segment usually does — and a number nobody published is worth less than an admitted gap.

Not published for this floorplan: GVWR, interior height, sleeps, slide count, axle count, tire specification, awning, refrigerator, air conditioning. If you find one of these in a manufacturer document for this plan, it belongs on this page.

The completeness figure at the foot of this page (75%) measures the same thing on the full field set: it is a measurement of how much this floorplan’s manufacturer publishes, not of how much research went into the page.

How every figure here was sourced and checked is set out on the methodology page.
