Hey Scott,
I try to stick around the payload capacity of the vehicle when choosing this type of suspension enhancement. Anything more is pretty much just overkill and can sometimes negatively affect your ride quality. The SuperSprings Custom Suspension Stabilizer and Sway Control Kit # SSA16MXKT has a 1,650lb load leveling capacity, which is almost twice what you're hauling so it'd be the better option unless you plan on hauling heavier in the future. SuperSprings only activate as weight is added so they're one of the better options to keep your ride quality the same as when you're unloaded
You'll need to special order u-bolts (5-1/4") if the leaf spring stack height is greater than 2-3/4" at the axle.
