2026 Forest River Aurora31KDS

The Aurora 31KDS leaves Forest River's factory at 7,743 lbs dry, with a published GVWR of 10,000 lbs and 2,257 lbs of cargo capacity between the two. Cargo capacity is 23% of the loaded rating, and Forest River's own definition is worth reading before you plan against it: cargo capacity is what remains for fresh water, gear, food, batteries and every dealer-installed accessory. Fresh water alone is 8.3 lb per gallon, so filling this trailer's 44-gallon fresh tank spends 365 lbs of that 2,257 lbs before anything else is loaded.

Dry tongue weight is 1,042 lbs, or 13% 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 44 gallons fresh, 70 grey and 30 black, 100 gallons of waste capacity against 44 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 Aurora roster this is the 6th of 11 floorplans by dry weight, in a line that runs from 6,468 lbs to 9,152 lbs. It sits in the middle of the line by weight. 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 the pair of weights is to stop planning against the dry figure. Nobody tows a trailer at 7,743 lbs: that is the weight before water, batteries, propane, bedding, food, tools and anything the dealer bolted on. Load half the published cargo capacity, which is modest for a family trip, and this plan is already near 8,871 lbs on the road. Compare that number against the tow vehicle, not the dry weight, and leave margin on top of it - the published GVWR of 10,000 lbs is a limit rather than a target.

Every number above was captured twice from Forest River and checked against itself before it was published. The line roster block and the individual floorplan page are two separate factory renderings of the same trailer, and this plan's 4 shared figures agree exactly on both. Dry weight plus cargo capacity also equals the published GVWR exactly, which is the arithmetic check this site runs on every profiled floorplan. Where a figure is missing from this page it is because Forest River does not publish it in this channel, not because it was hard to find - and the row says so rather than being quietly dropped.

Forest River's own description of this floorplan reads: “Designed for outdoor enthusiasts seeking comfort and space. Dual slides create a roomy interior with a front private bedroom and ample storage. A 21-foot awning expands your outdoor living area for relaxing evenings at the campsite.” That is the factory's marketing copy rather than a specification, and nothing in it is treated as a verified field on this page - layout descriptions, sleeping arrangements and feature claims in factory copy are not carried into the spec table unless the factory also publishes them as specifications.

Three Aurora floorplans the factory publishes for 2026 that this catalogue did not carry, all of them at the long end of the roster: 7,124 to 8,154 lb dry on lengths of 33 feet 7 inches to 36 feet 3 inches, with dry tongue weights of 888 to 1,054 lb. Forest River publishes a GVWR for all three and dry weight plus cargo capacity equals it exactly on all three.

This floorplan carries its water comfortably. A full 44-gallon fresh tank is roughly 16% of the 2,257-pound cargo capacity, leaving the 31KDS with a usable gear budget even when you tow full.

The published dry tongue weight of 1,042 pounds is 13% of the 7,743-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 10,000-pound GVWR the 31KDS is towing 2,257 pounds more than its 7,743-pound dry figure, and that is the number your vehicle has to be rated for — not the brochure weight.

Tank balance is generous here: 44 gallons of fresh against 70 grey and 30 black, so waste capacity keeps pace with supply and the fresh tank is the constraint that ends a dry stay.

Ranked by GVWR, the 31KDS sits 6 of 9 in the Aurora line: 10,000 pounds against a line that runs from 8,468 to 10,686 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: Aurora 29TQS is 176 pounds lighter at 9,824 lb GVWR; and Aurora 32RLTS is 342 pounds heavier at 10,342 lb GVWR.

Against the 31KDS: the Classic 30RB is 5 ft shorter; the Campsite Reserve 29TJ is 5 lb lighter; the Cascade 29TEC is 5 lb lighter. 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 Aurora floorplans profiled here run 6,468 to 9,152 pounds dry and 30 to 38 feet of exterior length across 9 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 Aurora line hub.

This catalog tracks 18 specification fields per floorplan. Named sources publish 11 of them for the 31KDS. 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, sleeps, slide count, axle count, tire specification, 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 (85%) 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.
