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 (17,320 lb) and the upper loaded pin estimate (4,330 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 3715GX
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
12,884 lb dry and 16,925 lb GVWR, against this model’s 14,254 lb and 17,320 lb.
16,354 lb dry and 21,000 lb GVWR, against this model’s 14,254 lb and 17,320 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), 41% of the Sandstorm / Stealth / Shockwave 3715GX’s 3,066 lb cargo capacity, leaving 1,821 lb. Across 10 Sandstorm fifth-wheel floorplans the water share runs 22% to 41%, and this plan’s is the highest. Nearest on that share: Sandstorm 3513GX at 38%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.120 S10.4.3).
