2026 Forest River Sandstorm / Stealth / Shockwave2900

The Sandstorm 2900 leaves Forest River's factory at 9,399 lbs dry, with a published GVWR of 13,855 lbs and 4,456 lbs of cargo capacity between the two. Cargo capacity is 32% 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 102-gallon fresh tank spends 847 lbs of that 4,456 lbs before anything else is loaded.

Dry tongue weight is 1,855 lbs, or 20% of the dry weight. Ten to fifteen percent is the conventional band for a bumper-pull trailer, and this plan sits above 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 102 gallons fresh, 80 grey and 40 black, 120 gallons of waste capacity against 102 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 Sandstorm roster this is the 5th of 15 floorplans by dry weight, in a line that runs from 7,439 lbs to 16,354 lbs. It sits in the lighter 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 the pair of weights is to stop planning against the dry figure. Nobody tows a trailer at 9,399 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 11,627 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 13,855 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 listing 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 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. 2900 is a Sandstorm designation and this site does not decode it into a layout claim.

Sandstorm is a toy-hauler roster published under three badges at once, and the first useful thing to know about it is that Sandstorm, Stealth and Shockwave are the same sixteen trailers. Not similar - the same floorplan codes, the same dry weights, the same cargo capacities, the same tanks, checked field by field. So a shopper cross-shopping the three badges is cross-shopping one product, and the choice between them is a dealer question rather than a trailer question. Within that roster there are two real classes. Five plans are travel trailers, 7,439 to 9,399 lb dry with 1,155 to 1,855 lb on the tongue. Seven are fifth wheels, 9,459 to 15,749 lb dry with 2,165 to 3,765 lb on the pin. The lightest fifth wheel outweighs the heaviest bumper pull, so the two halves do not overlap and no plan here is a borderline call. Cargo capacity runs 3,281 to 5,676 lb on the fifth wheels and 3,771 to 5,300 lb on the travel trailers - the bumper pulls give up very little payload, which is unusual and is the reason to read the table rather than assume the fifth wheels carry more.

A full 102-gallon fresh tank is about 851 lb of water (water counts as cargo: 49 CFR 571.120 S10.4.2), 19% of the 2900’s 4,456 lb cargo capacity, leaving 3,605 lb. Across 5 Sandstorm travel-trailer floorplans the water share runs 16% to 23%, and 2 give up more than this one. Nearest on that share: Sandstorm 2730 at 17% and Sandstorm 2600 at 19%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.120 S10.4.3).

Closest sibling: the Sandstorm 2600, nearest on the published figures. It differs on 6 of the 8 fields both publish (this plan first): length 36 ft 6 in vs 34 ft 9 in; dry weight 9,399 lb vs 9,129 lb; GVWR 13,855 lb vs 13,570 lb; cargo capacity 4,456 lb vs 4,441 lb; dry hitch weight 1,855 lb vs 1,570 lb; black tank 40 gal vs 42 gal. They match on fresh tank and grey tank.

Either side of it by GVWR: Sandstorm 2600 is 285 lb lighter (13,570 lb GVWR).

All 12 Sandstorm floorplans: Sandstorm line hub.

Against the 2900: the Puma Vista 401RLFT is 45 lb heavier and 6 ft longer; the Jay Flight 40LOFT is 95 lb heavier and 4 ft longer; the Eagle 325BHQS is 105 lb lighter and 1 ft longer.

10 of the 18 fields this catalogue tracks are published for the 2900. Not published: interior height, sleeps, slide count, axle count, tire specification, awning, refrigerator, air conditioning.
