2009 Strange Sifting

I have experienced strange shifting when pulling my 23 foot ultralite trailer. Flat road no wind and it seems that the 5.7 l V8 does not have enough power to maintain 60 MPH and the 6 speed transmission shifts from 5th to 4th every 5 miles just to keep a constant speed. The dealer has recalibrated my computer twice and now wants to adjust fuel ratio. It this a good idea? Fuel consumption has doubled since this shifting problem has started. I pulled my trailer for 2 summers without much problem, but last summer was fustrating with this problem.
