Welcome to the forum and glad to hear about your successful first season. Winterizing isn't that hard to do, just remember to follow a sequence and don't forget anything. As for covers, everyone has an opinion, do what works for you. Enjoy the winter, the cold weather seems to always last too long, but it will give you some time to check the forum for ideas and hints on how to use your RV and maintain it.
Again, welcome, enjoy your time with us.
