2026 Forest River Sandstorm / Stealth / Shockwave4114GX

The Sandstorm 4114GX has 5,251 lbs of cargo capacity between 15,749 lbs dry and its 21,000 lbs GVWR, 25% of that rating; filling its 150-gallon fresh tank at 8.3 lb a gallon uses 1,245 lbs of it (how to read trailer weights).

Pin weight is 3,360 lbs, 21% of the dry weight as published; it rises as the trailer is loaded and comes off the truck’s payload, not its towing rating, so check it against the payload on your own door sticker (pin weight and payload).

Off hookups: 152 gallons of grey and black capacity against 150 gallons of fresh water, so fresh water runs out first (tank sizes by length).

Against the rest of the Sandstorm fifth-wheel roster this is the 7th of 7 fifth wheels by dry weight, in a line that runs from 9,459 lbs to 15,749 lbs. It is the heaviest fifth wheel in the line, so the tow vehicle should be settled before the floorplan is.

Plan the tow on loaded weight, not the 15,749 lbs dry figure: half the published cargo capacity brings this plan to about 18,375 lbs, and the published GVWR of 21,000 lbs is the limit (how to read trailer weights).

Forest River’s line listing and this floorplan’s own factory page agree on all 4 shared figures. Dry weight plus cargo capacity equals the published GVWR exactly. A missing row means Forest River does not publish that figure (how figures are verified).

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. 4114GX is a Sandstorm designation and this site does not decode it into a layout claim.

How the 4114GX differs from the other six Sandstorm fifth wheels. Most distinctive first. How these ranks are worked out.

• Dry weight, 15,749 lb: heaviest of seven; next is the 4017GX (15,674 lb).
• Pin weight as a share of dry weight, 21.3%: smallest of seven; next is the 2800 (21.7%).
• Length, 45 ft 11 in: longest of seven; next is the 4017GX (45 ft).
• Black tank, 32 gal: smallest of seven; next are the 2710, 2800 and two others (40 gal).
• Pin weight, 3,360 lb: second-heaviest of seven, between the 3513GX (3,250 lb) and the 4017GX (3,765 lb).
• Cargo capacity, 5,251 lb: third-smallest of seven, between the 3217GX (4,036 lb) and the 2710 and 2800 (5,300 lb).
• Cargo capacity as a share of GVWR, 25%: third-smallest of seven, between the 3217GX (23.5%) and the 4017GX (25.4%).
• GVWR, 21,000 lb: highest of seven, level with the 4017GX; next is the 3513GX (17,250 lb).
• Exterior height, 13 ft 5 in: lowest of seven, level with the 2710 and 2800; next are the 3217GX, 3300 and two others (13 ft 6 in).

Next to the 4017GX, the nearest lighter floorplan by dry weight, the 4114GX is 75 lb heavier by dry weight, has 75 lb less cargo capacity, has a pin weight 405 lb lighter, is 11 in longer, stands 1 in lower and has a black tank 48 gal smaller; the two publish the same GVWR, fresh tank and grey tank.

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 150-gallon fresh tank is about 1,245 lb of water (water counts as cargo: 49 CFR 571.120 S10.4.2), 24% of the 4114GX’s 5,251 lb cargo capacity, leaving 4,006 lb. Across 7 Sandstorm fifth-wheel floorplans the water share runs 22% to 38%, and 2 give up more than this one. Nearest on that share: Sandstorm 2710 at 23% and Sandstorm 3217GX at 31%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.120 S10.4.3).
