i have a question about building a pole barn (32' span)
can i build it with:
4x6 posts - 8' oc, 2x6 trusses - 4' oc?

and if i nail a 2x4 onto the side of the 4x6 (making a 4x8) will it be as strong as a 6x6 or at least strong enough for my building??? or would 'laminating' (with pl400 or the like) a 2x4 on to a 4x6 make it as strong?

thanks!
