About the same as others here. I've got the 7.3, Crew, Short bed, 4.30 gears, right at 1,000 on the clock. My first towing will be this weekend hopefully. It's been WINDY AS HECK here and I've been seeing 12.7 or so with mixed driving. Was hoping for a bit better but with the size and wind etc., still pretty happy. My 12 Eco only got a couple better. I'm also hoping that while towing I get better than the Eco did at 6-7.
