I have an F250 but it will be the same as the SRW F350's. Prior to level kit and MT's.. Here's a pretty good estimate of what mpg's I'd get at what speeds. 3.55's.
80mph - 16
70mph - 18
60mph - 19
50mph - 20
Towing my 15-16k lb 42' Toy Hauler... 7-8 mpg at 70... I tow rarely (maybe 3 times a year for 500-1000 miles total so far on my 2013) but I think in the future I'll slow it down to 60 mph for safety reasons and to hopefully squeeze some more miles out of my 26 gallon tank.
Mixed interstate, town, decent on the foot pedal, around 15-16 mpg... I have 28,000 miles and hand calculate every tank and my display has never been more than 1mpg off of what the hand calculation is.
With the level kit and heavy MT tires I lost 1-2 mpg depending on the speed.
