2026 RockwoodUltra Lite 2606WS

The Rockwood Ultra Lite 2606WS is the natural step up from the Mini Lite line for couples who want more trailer. At nearly 30 feet with dual slides, it pairs a private rear bath with a front bedroom that gains a dedicated wardrobe slide — a small luxury that adds real hanging and storage space — and opens the main living area with a second slide. Nominal capacity is three, but the layout is built for two who want room to spread out. It has a direct twin in the Flagstaff Super Lite 26RBWS.

Moving to the Ultra Lite class brings bigger holding capacity: a 90-gallon grey tank and a 45-gallon black tank, roughly triple the smaller Mini Lite plans, which transforms how long the trailer can go between services on a longer trip. The build is the same Forest River package scaled up — six-sided aluminum frame, laminated composite walls, a laminated walkable roof under a lifetime limited roofing warranty, an enclosed heated underbelly, and the standard 200-watt rooftop solar with an 1800-watt inverter.

At 6,550 pounds dry against an 8,542-pound GVWR it leaves 1,992 pounds of payload — a healthy margin for a couples' coach — though the higher GVWR means a well-rated half-ton or a three-quarter-ton is the right tow vehicle. For couples graduating from a lighter trailer who want a private rear bath, a wardrobe slide and the tank capacity for extended stays, the 2606WS is the Ultra Lite line's accessible entry point.

Forest River's Rockwood and Flagstaff are near-identical twin lines — the same trailers built on the same chassis, differing mainly in interior décor and badging. They split into two weight classes: the lighter Mini Lite (Flagstaff calls it Micro Lite) and the heavier Ultra Lite (Flagstaff Super Lite). The 2606WS on this page is highlighted; each other profiled plan links to its own page. Across both nameplates and classes the family runs to dozens of floorplans; the highest-demand layouts are detailed here and the rest are catalogued on the line hub.

This floorplan carries its water comfortably. A full 54-gallon fresh tank is roughly 23% of the 1,992-pound cargo capacity, leaving the Ultra Lite 2606WS with a usable gear budget even when you tow full.

The published dry tongue weight of 742 pounds is 11% of the 6,550-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.

Nothing above changes the ceiling. Loaded to its 8,542-pound GVWR the Ultra Lite 2606WS is towing 1,992 pounds more than its 6,550-pound dry figure, and that is the number your vehicle has to be rated for — not the brochure weight.

Tank balance is generous here: 54 gallons of fresh against 90 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 GVWR, the Ultra Lite 2606WS sits 5 of 8 in the Rockwood & Flagstaff line: 8,542 pounds against a line that runs from 6,794 to 9,989 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 & Flagstaff Mini Lite 2523MBR is 832 pounds lighter at 7,710 lb GVWR; and Rockwood & Flagstaff Ultra Lite 2706BH is 48 pounds heavier at 8,590 lb GVWR.

Against the Ultra Lite 2606WS: the Puma 26FKDS is 11 lb heavier and 1 ft longer and sleeps 2 more; the EVO 2985VBX is 29 lb heavier and 4 ft longer; the Airelume 270 is 39 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 & Flagstaff floorplans profiled here run 5,132 to 8,149 pounds dry and 24 to 35 feet of exterior length across 8 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.

Every profiled floorplan in this line, with the full weight table, is on the Rockwood & Flagstaff line hub.

This catalog tracks 18 specification fields per floorplan. Named sources publish 16 of them for the Ultra Lite 2606WS. 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: interior height, tire specification. 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 (95%) 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.

Values on this page carrying an asterisk were derived by arithmetic from published figures, or come from a single source, rather than being printed directly by the manufacturer. The flag travels with the number into the downloadable spec sheet.

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