The duals will probably increase the area between the tire and shield by at least 10 inches. Duals will help over 30.5's. However it will take you farther. Sometimes that's good, sometimes it takes you far enough in you can't get it out. We had our 62 with duals and RWA stuck a few times and always managed to get it out with a 4WD and 100,000 lb stretch rope. Tracking down the row is better as the tendency to wander is reduced. The big dis advantage is the transport width. We are 25 miles east of St. louis in a fairly populated area and we have to be careful what time of day we move it.
