30 MPG Documentary

I recently picked up a 98.5 2500 2x4 short bed that had some money thrown at. I decided to take it to the next level and do everything possible to get 30 MPG when empty at 65 mph. I live in a 5th wheel camper and travel for a living, so diesel costs add up!

Please give me your best ideas to improve MPG.

Here is what I've done so far.

  • Front End Aerodynamics on the grill & lower bumper shroud & tonneau cover ( Considering a belly pan underneath )

  • RV 275 Injectors with 7 holes ( Are there better injectors out there for economy ? )

  • 19.5" tires that leave me at about 1750 RPM @ 65 mph with 3.55 gears

  • Quadzilla with an economy tune ( Hoping to get a custom tune when all hardware is done )

  • 205 degree thermostat ( higher temp leads to more complete combustion ) I have an upgraded radiator for pulling

  • Borg Warner K27 turbo ( 18 cm^2 exhaust outlet volume is 50% larger than a stock HX35 at 12cm^2 thus reducing back pressure )

  • AFE Bladerunner GT Series intercooler 3" thick ( denser air burns fuel more completely )

  • Full Lock Up Torque Converter

  • 15" Dual Electric Fans ( Stock fan clutch eats 20+ horsepower according to some estimates )

I'm looking for a used gear vendors overdrive as that would get me to 1500 RPM @ 65 Mph

What ideas do you have ?
