Just make sure that your truss are correctly spaced, bottoms and tops are straight and that the truss is standing tall, not leaning to one side ...i.e., align them and as "Gator" said, nail away. I am assuming the walls to which you are attaching the truss are plum and flat on top. Oh yes, if you were down here you should make sure the hurricane straps are on in acord with the code.
