My long trips, two of em. From South Central Arkansas to Luckenbach/Fredericksburg TX, about 1,300 miles round trip X two. The first trip was with the stock 4.57's (stock 3/4 ton gears) with a T5 transmission. Second trip was with 4.11 gears. Much better road gear. With the .72 overdrive T5 and 4.11's 60 mph is a very OK cruise speed with 65 to 70 if required. Best is in the mid to high 50's though and if not holding up traffic my normal speed.
