I got a new 30 on Amazon Prime Day. I want to leave it outside, but I want it to be safe and dry when not in use. I'd like to build a small wooden box around it, like the one in this thread (just smaller): http://www.smokingmeatforums.com/t/111337/ready-for-winter-or-bad-weather Do I need to use pressure treated lumber for the inside framework, or can I use normal lumber? I will be sealing the outside wood. The inside framing of my shed is not pressure treated (none of the sheds I have seen are), so I would think that as long as the outside of the box is treated for water resistance, I don't need to worry about the inside. It will also be up off the ground on casters, so no direct ground contact for the wood.
