One thing we found out that made living easier.
Go to a car wash once a week , clean and vacuum the camper inside and out. Toss your clothes in a washing machine in a local laundrymat while you are doing it..

If you take a wrong turn somewhere and end up in Denmark, give me a call, we'll figure something out.
