Danny, You are right about the cost. They are expensive but on the other hand they are pretty easy and quick to put up and I suppose you could finish enclosing them with more metal. I wanted to build a pole barn but for some reason that I cannot understand my wife objected very strongly yet she had no problem with the carport. Since I don't live on the land where my tractor is kept at this time, it is probably better that I got the metal carport since it would be easier to move if I decide later that I put it in the wrong place. Logically the best place for me to put a barn to store the tractor in is on part of an old asphalt road because I would not have to put a foundation under a pole barn but I chose to put the carport in the woods so it would not be as easy to spot by unwelcome visitors. I use 16"x16"x4" concrete blocks to keep my implements off the ground.
