First, no pics yet. They will be coming. I have a 12x10 prefab metal shed that holds all my lawn and garden tools that I am relocating to the edge of my driveway near the garage. It will be under a maple where I typically do my splitting. I plan to build a 12x16 lean-to off the side for a wood shed. It will just be a metal roof pitched about a foot front to back, no walls. I already have 1 cord of hickory and ~1/2 of white oak stacked on pallets where it will be under the shed. I have what I hope to be about 3 more cords of red and white oak and 2 cords of locust to split. If I place the 4'x4' pallets 3 deep x 4 long and stack 6' high I should get 9 cords under the roof. If I leave a 3' gap between the pallets to walk and for airflow then I only get 6 cords but better access to it and better ventilation. My question is: Should I stack as much under the roof as I can or would I be better off to leave space between the stacks for better airflow and let some of the wood end up not under the roof?
