Doug does a thorough hand wash and wax every time we come home from a trip, hits the windows with a bucket and squeegee every couple of days and we give it a good wash at a truck wash every week or so when we are traveling. We may debug more frequently, as needed.
Why have something so beautiful, and that we love so much, and not keep it sparkling clean, we say.
People ask us all the time if it is new. No, just well-cared for.
