Answer to: Best Rear End For Running Reefer In The WestI'm shopping for a T660 which I'm going to be using for dry van. I have had loads as light ad 1200lbs up to copper coils that are about 45000lbs. Mostly I'm in the 30000lb range. I'm trying to find a good trans/rear gear combo. I'm a national driver, so all 48, I do avoid east of the Mississippi if I can. I would like to be able to cruise 10, 40, 70, 80 out west at around 75. There seems to be a hundred ways of doing it. I'm not overly concerned about fuel mileage. I would like to stay above 6.5. 450hp Cummins. Suggestions from you experienced folks would be great.
