I'd put walls up first man.
Are you not entertained?!?!
Uh oh, shit just got real. We raised my big huge attic trusses with 4 people, we got 95% done in one day... had to use a crane by myself on the last 5%. Went MUCH faster with the crane, as you can imagine, but I only had to pay the three guys that helped me with some lunch and parting gifts.
Looks like a GTG at Al's when the walls get put up, straightened and braced, and we will slap those trusses up in an hour. We will have the roof under ply in a half day, tar paper by the end of the day...no problem!!!
