I guess the mileage is possible. We had a neighbor when we lived in Southern California who bought a new S.O.B. coach. He soon found that a 102  inch wide coach plus  7 inches of mirrors on either side for a total width of 116 inches or 9 ft 4 inches, only left  4 " on either side on 10 ft secondary and city roads, and 14" on freeways. Hence, the only travel he did was an annual trip to Quartzsite Arizona every January, putting only  500 miles per year on his coach.
