Welcome to FTE klaw37!
Is this a new truck? V10 or PSD? Does it have a 4.10 rear gear? That RPM:MPH sounds about right for a V10 with a 4.10.
Find out what gear you have and the tire size then google "rpm calculator". You will be able get an approximate calculation.

Sorry guys, its a 99 7.3L, dually, automatic. I was pulling a little motorcycle trailer about a 450 mile trip and got 12.5 mpg! with the cruise on! is this all I can expect? this is my first 1 ton, been driving big trucks for 20 yrs. It's got a 4" wide open exhaust also.
