Motor Trend says the curb weight of a Double Cab V6 Automatic 4x4 is 4,480 lb. GVWR is 5,600 lb. So the cargo capacity is (5600-4480) = 1,120 lb.
I saw these numbers down near the bottom of this page

Searching the web, I found this cargo capacity number confirmed by several other websites.
Toyota says the 5600 lb GVWR is the same for all models (in other words, the suspension and brakes are the same for all Tacomas). So if your truck curb weight is lighter (Access Cab, 2WD, I4, for example) then the cargo capacity will be higher.
