Looks like a drunk put it together, LOL! Nothing plum , nothing level, and nothing measured ! It should work and seems strong enough for Winter. It really won`t need to hold up to 6 inch's of snow if I keep it heated and full of goodness anyway, LOL! Really could have done a better job on them but it started out on uneven and unleveled ground and I`m kind of rushing trying to do bunches of different projects all at once before Winter hits. Like I`ve said before," I should leave the carpentry to Jesus ! "
