I just wanted to post an update on my progress so far. I decided to use vinyl siding instead of T1-11 for the siding and my uncle is giving me leftover metal roofing from his garage for free for the roof. I got 7/16” OSB to sheath the walls and roof. I got the sheathing on all the walls and then assembled all the trusses and started putting them up today, but then I got rained out before I could finish. The trusses are 16” O.C. with a foot overhang on each side.
Here are some progress pictures:
