I also got 8mpg towing a 24' 6,000lb travel trailer. The 6.4 sucks it down compared to any of the diesels of that generation, but it never struggled either. Even with H&S Tunes I didn't see a drastic improvement some others might have seen. Highway pre-delete I saw 14mpg deleted I saw maybe 16mpg if I was lucky.
