I built an 11' x 12'3" lean to with 6x6's on the corners. I would like to put up walls for privacy and security. Would 2x6x12's be strong enough to span the 6x6's so I can put up some t1-11 or composite type siding? I am trying to avoid putting additional posts in the ground. Also trying to keep the cost low and hide my rider, atv and other equipment from prospective looters. Any suggestions? Thanks
