Forest RiverSierra

Sierra's published pin weights spread further than its dry weights do, and that is the fact worth carrying into a dealership: nine floorplans run 10,319 to 13,864 lb dry - a 3,500 lb band - while pin weight runs 1,560 to 2,825 lb, nearly doubling. Two Sierras a thousand pounds apart on the scale can be far apart at the pin too. Every plan on the roster ties out exactly against its published GVWR.

Across the whole Sierra roster the published dry weights run from 10,319 lbs to 13,864 lbs, cargo capacities from 2,431 lbs to 3,456 lbs, and pin weights from 1,560 lbs to 2,825 lbs. Exterior lengths run 36 to 44 feet. Those are Forest River's figures for a standard build, captured from the factory line listing and confirmed against each floorplan's own factory page.

Forest River publishes a GVWR for 9 of the 9 floorplans, and on 9 of those the arithmetic ties out exactly: dry weight plus cargo capacity equals the published rating to the pound. That check is run on every plan before it is profiled here, and a plan that fails it is catalogued with the disagreement printed rather than quietly corrected.

7 of the 9 Sierra floorplans are profiled in full below, each on its own page with the complete factory weight, dimension and tank block. The profiled set is spread across the weight range rather than taken from one end of it, so the lightest and heaviest plans in the line are both represented. Every plan profiled here publishes a full field set and, where Forest River publishes a GVWR, passes the dry-plus-cargo arithmetic check.

The remaining 2 Sierra floorplans are catalogued here from the factory's published figures. 2 of them are Forest River dealer-stock-only plans, which are real floorplans but are not orderable through the normal channel. A plan is catalogued rather than profiled when the factory has not yet published its full field set, when its own published figures disagree with each other, or simply because the profiled set is capped. Nothing in this table is estimated.

Forest River’s 2027 Sierra roster, read 22 Oct 2026: twelve floorplans. It is a separate record from the 2026 sections above and nothing is merged between them. Six floorplans carry over and keep their 2026 pages, each now showing its 2027 record in a block of its own; 3100RD, 3480RL are new for 2027. Listed without a page here — 3280ML, 3870HBRK, 3905DB: every figure TBD. 4003MB: 2027 figures pending: Forest River’s printed weights do not add up; the 2026 page stays. Unloaded weight plus cargo capacity equals the published GVWR exactly on every plan with a full record. Two plans from the 2026 roster are not on the 2027 one; any page built for them remains as the 2026 record.

Sort this line by the constraint you actually have. If the truck is fixed, start at the weight column: the lightest plan in the roster is the 3370RLS - DSO at 10,319 lbs dry and the heaviest is the 3844QUAD at 13,864 lbs, and that spread is wide enough that the two ends are not the same buying decision. If the truck is not fixed, sort by cargo capacity instead - the 3550BH - DSO carries the most at 3,456 lbs, and payload is the number that runs out first on a long trip.

Do not sort by floorplan number. Forest River's codes encode length loosely and layout not at all, and this site does not decode them into layout claims. Two plans with adjacent numbers in this roster can differ by hundreds of pounds of dry weight and by more than that in pin weight, which is the figure that determines what the truck has to be.

Where Forest River publishes a floorplan description it is quoted on the plan page and identified as factory marketing copy rather than a specification. Where it publishes none, the plan page says so instead of describing a layout that nobody has verified. That is the difference between a catalogue and a brochure.
