I'm moving from Korea to Rapid City South Dakota in Jun and thinking about getting a 5th wheel or toyhauler since I have a Harley. I retire in about 18 months and don't want to pay the rent. I had a class c a few years ago but didn't use it much. I would be by myself but I'm worried about the winters and keeping the water/sewer from freezing. Any suggestions on the best brands to look at or how bad it would be full time in South Dakota climate. How are the stackable washer/dryer units. Air Force girl with lots of questions from Korea....HELP
