Before I make anything like that out of treated lumber I purchase the lumber. Then I store it in my shop for a month or so with room around each board for ventilation. This allows me to weed out boards that will warp and they get their shrinking done before construction. And as a nice benefit, the wood can weigh half as much so it's much easier to handle bigger projects.
