I got a quote for a 32*40*10. And im rethinking the length. I may add another 10ft to it. 32by40 isnt all that big. ill have a LS tractor FEL for small chores and up keep but with a cab and other stuff to put in there. So I might see how much 10ft more would be. I cant imagine it would be all that much more. Sometimes these can be a head scratcher. But my garage will be a three bay garage so the tractor will be heated in the winter. We shall see. IF that 10ft extra space isnt much to add ill probably do it
