Evansblue, we get about 14-15 towing a 13,000lb horse trailer on the highway with our 06 Dmax. Here's how it goes down:

200 miles on truck: 16mpg
35,000 miles: 19mpg
60,000 miles: 21mpg
Duramax at the shop with close to 400,000 miles, 24MPG!!!!!!!!

These engines don't even get broke in until about 100,000 from what I've heard.
