SE SD | Shoot me an email if you want, i can get you the number to my builder. I know he built a bigger barn last year (80x160)? where he used 2, 3 or 4" posts with the truss sandwiched between the two. If you are on facebook, check out TRC steel buildings and fence. My posts are 3.5" and are 12' on center. My building is all steel, and all welded.
