Every number on this page was read on 7 Nov 2026 from Forest River’s own 2026 Sandstorm floorplan page for the Sandstorm / Stealth / Shockwave 3216GX, whose heading names the model year 2026.
How the 3216GX differs from the other nine Sandstorm fifth wheels. Most distinctive first. How these ranks are worked out.

- Cargo capacity, 4,041 lb: fourth-smallest of ten, between the 3217GX (4,036 lb) and the 4015GX (4,646 lb).
- Pin weight, 2,925 lb: fourth-lightest of ten, between the 3300 (2,555 lb) and the 3217GX (3,160 lb).
- Pin weight as a share of dry weight, 22.7%: fourth-smallest of ten, between the 2800 (21.7%) and the 2710 (22.9%).
- Length, 37 ft 9 in: fourth-shortest of ten, between the 3300 (36 ft 10 in) and the 3217GX (38 ft 4 in).
- Cargo capacity as a share of GVWR, 23.9%: fifth-smallest of ten, between the 3217GX (23.5%) and the 4114GX (25%).
- Black tank, 32 gal: smallest of ten, level with the 4114GX; next are the 2710, 2800 and two others (40 gal).
- Exterior height, 13 ft 5 in: shared with the 2710, 2800 and two others; of ten, one lower and four taller, nearest the 4015GX (13 ft 4 in) and the 3217GX, 3300 and two others (13 ft 6 in).

Towing it
Check your vehicle. Enter the ratings from your owner’s manual and the door-pillar placard.
Compares your figures with this page’s published GVWR (16,925 lb) and the upper loaded pin estimate (4,231 lb, a rule of thumb). Your vehicle’s placard and the trailer’s own weight label govern.
Loaded range: 15–25% of GVWR on the pin, a rule of thumb, not a measurement of this unit. No truck ratings or hitch classes (why; NHTSA, DOT HS 809 433). The range starts at the published figure, because loaded is never lighter than that.

04 Notes on this floorplan
What Forest River does not publish for the Sandstorm / Stealth / Shockwave 3216GX
Forest River prints no tire size, interior height, sleeping capacity for this model, so none is given. Nothing is filled from a sibling model, a different model year or a dealer listing.
Read the label on the trailer
Federal rules put a load-carrying label inside every RV trailer: its unloaded weight with full propane, its cargo carrying capacity and its GVWR (49 CFR 571.110 and 571.120). Those figures come from the trailer itself and govern the towing decision.
05 How it compares
14,254 lb dry and 17,320 lb GVWR, against this model’s 12,884 lb and 16,925 lb.
06 Loading it for a trip
A full 150-gallon fresh tank is about 1,245 lb of water (water counts as cargo: 49 CFR 571.120 S10.4.2), 31% of the Sandstorm / Stealth / Shockwave 3216GX’s 4,041 lb cargo capacity, leaving 2,796 lb. Across 10 Sandstorm fifth-wheel floorplans the water share runs 22% to 41%, and 3 give up more than this one. Nearest on that share: Sandstorm / Stealth / Shockwave 4015GX at 27% 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).
07 Where this floorplan sits
Closest sibling: the Sandstorm 3217GX, nearest on the published figures. It differs on 6 of the 8 fields both publish (this plan first): length 37 ft 9 in vs 38 ft 4 in; dry weight 12,884 lb vs 13,124 lb; GVWR 16,925 lb vs 17,160 lb; cargo capacity 4,041 lb vs 4,036 lb; hitch weight 2,925 lb vs 3,160 lb; black tank 32 gal vs 40 gal. They match on fresh tank and grey tank.
