. . '06 2500 quad cab lwb 4x4 that has 22,000 miles on it. He said it has leather interior and a gooseneck. Everything looks to be in pretty good shape. After his trade-in, he said he can get it for around $27,000. Is this a pretty good deal? He's leasing a truck right now and is about to go over his mileage limit. One of the main things I've told him to check is the rear end gear ratio because he probably will not be pulling a lot of weight very often, so for better mileage I suggested that it should have a 3. 73. Any thoughts or suggestions?
