depends on how fast you were going. Going through those mountains can make a big difference as well. Also, how much did this trailer weigh? can be a big factor as well.

Fill out your signature so we know what we are dealing with on your truck. Larger injectors? Fuel pump cranked? Turbo? Timing, etc.

Just dropping back to 65mph is good for 1 - 2 mpg

what was your mpg with the a518 or 727 or whatever you had before just driving unloaded? and you've gotten 20.5 with the 47rh just driving unloaded??
