Interesting posts ... mostly from man's point of view. LOL. When we went from Class C to Class A both of us had to get used to the 'wider' feel and again when we went from 8' to 8.5' width we both had to adjust again. My husband, who does most of the driving (but not all), thought I was making too big a deal with the 8.5' adjustment UNTIL HE SAT IN THE PASSENGER SEAT!
I still get a little anxious when we are on narrow roads with no verges, roads with no stripes dividing the lanes and when there is no outside stripe delineating road/lane edge.

P.S. Rear view camera does help to tell driver that he is or is not centered in his lane BUT it shows where you were not where you are headed.
