So I went to versatubes website sorry I kept calling it versamax lol I designed this it's a 36x40x12 they only offer 8' wide doors I'm gonna try to email them and ask if they have larger ones available. You can get the idea of how I want to lay mine out @John Dirks Jr i do have a 200 amp panel and two spares both double pole one is 20 and one is 30 could I swap one of those out for a 60 or 70?
