Poor MPG on the diesel

Vehicle2008 Ford F-350 Super Duty XL 4dr Crew Cab SB (5.4L 8cyl 6M)
ReviewThe truck is great for sure. I have owned Ford super duty truck since they started. This 2008 is all around best ford F-350 out there, but I have 8k miles on it now and tody is the 1st time i pulled my 40 fifth wheel. The MPG stinks. I got 7.8 at 65mph. Yes I have the 4.10 rear end. I think as soon as my warranty is up I will pull the exhaust system out and change it. I have been told this will make about a 40% better mpg. When I drive the truck without pulling anything it gets 12.2 mpg at 70, 13.8 at 65 mph, 16.0 at 55mph. I know I bought the truck to haul and yes that part is perfect. My last 350 got 17 mpg at 80 mph, pulling a 40 trailer I got 10.4.
