New TT owner here from SC as well. Having a time deciding between building a shelter or purchasing a cover. Found a great deal on a nice cover which would be much more cost effective at the moment. Is one better than the other? We are on the coast, so heavy sun and potential high wind. The cover I am looking at has a door access which is key for us because the kids play in it even when not on the road. Does a cover promote more mildew in a high humidity area? Want to take the best care possible of her. I welcome your opinions.
