Well, Bluedog, you have no insight into the person driving the RV. It could be someone who is new to driving an RV. Maybe it is the first time they were driving the RV in an area that has grades, and passing lanes, and the need to control speed. Maybe it was their first time on that road, with uncertainty of the lanes. When to move over? How long before I have to move back? Sometimes it may be best to stay the course if you are unsure. I feel some people should have more consideration, understanding, and compassion for other people. Possibly you, and the truck driver are the black eye?
