Any experience with those metal RV carport companies?

Mine came from Carolina Carports and they came when they said they would but one of the workers dropped a side panel and bent it. I called them and they sent a crew the next week and replaced it. Mine is fully enclosed. They did not have a door as large as I wanted so I had a local metal place build and install a 12' x 15' door for the front of it.....As we are having a tropical storm right now I am glad the rain and debris blowing around will not end up inside or on my 5th wheel...
