This garage will be just for the 46. I have a 35x75 with 12" ceilings in it for all my grease monkey stuff. I'm just going to us this one for tinkering on the 46. 24x30 is as big as I can go in my back yard due to property lines and drain fields. And township rules and regulations say I can only go as high as my house. So I can only go with 8" walls.

Here is a picture of my other garage.
