You're correct about snow load as we have very little.
What I've read on some DIY construction sites is to pay attention to the hinge effect. In other words the joint between the 8' & the 4' walls as much horizontal stress will try to separate the walls. Nails are only to be seen as temporary fasteners and to use 1/4" diameter carriage bolts every 24" as connecting devices. That's the same way I tied the top cap together as per code and I'll probably throw in some construction adhesive to boot. New hurricane ties will also hold the top cap & the trusses together.
I'll also build a wooden jib crane to raise the prefab wall extensions.
Thanks for the input.
