You do know its not solid right?
Does it really matter? The bolts holding the hitch on or the reciever pin will fail before you rip the sides out of that reciever. Stuffs like 1/4" isn't it? When under a shear load, that steel will be plenty strong enough. And even then, it's the D-ring pin and the reciever pin that are in shear. Personally, I wouldn't worry about the reciever being hollow.
