I know it's more $$ out of pocket, but I'm getting to the point where I'd rather spend some $$ and save my energy for the project. Just with the trusses alone, you'd be lifting about 3,000# and walking part ways up a ladder with it just to get them in place, not counting the I-joists. Would it be possible to plan ahead and get them all in place in one day if equipment was used? (Trusses and I-joists?)
If you need an extra hand, the offer still stands.
