I am curious what people get for mpg when towing? I had a 2002 5.3 for pulling a snowmobile trailer. The thing is not all that heavy but has a lot of wind resistance. I could pull 80 mph plus without a problem, but the thing liked the fuel. And there was no happy medium on the tach/shifting. I would be cruising along at 2200 RPM, but every hill bumped my up to 3200 RPM or way over. No way to run between 2400 - 3000 RPMs. Mileage was always 15 mph highway, but was a constant 7 mpg with the trailer. Haven't had the snow fly yet to see what my 2014 6 speed will do with the extra 35 HP, but curious what others have seen.
