I think you should go with 4.10s. With all my mods i get 16.5-17mpg on the highway. I got 14mpg towing 8500lbs. The gears really helped me with around town driving, and off the line. With as high of a first gear as the 4L80E has, 4.10 will help it off the line. Remember how important the 60' time is in the 1/4.
