Thanks for the correction. I did mean 3.73 rear end and not 4.73. The fiver we have been looking at is 40 feet and weighs in at 16,000 pounds. A dually is also our thinking when we test drive and these are typically hard to find at dealerships here in southeast Alabama. The input from you guys has been helpful so far and we hope for some more. One of you mentioned pleasing the DW and yes that is a top priority. When we had a one ton dually before, she only let me drive it when it needed fuel. Maybe this correction and additional information will elicit more wise suggestions.
