You are off to a good start. I suggest adding a Scangauge or Ultragauge. I think one or both of them can monitor transmission temperature.

The large difference in mileage when towing implies that your largest gains will come from improving the Tahoe/trailer aero interface or aero tweaks to the trailer. Post a photo with the trailer attached, maybe we can make a suggestion.

Mileage increases with tire pressure, but some vehicles need to run less than sidewall maximum because of traction. I'm running 50 PSI in my tires, where the sidewall maximum is 47 PSI.

Useful driving techniques include DWB and DWL. DWB is Driving Without Brakes. Time traffic lights and speed limit changes so that you don't use your brakes. DWL is driving so smooth that your passengers fall asleep.
