I tow a 15K RV with a 12'6 high flat front and can get 14 MPG any day. The tool I use is the ScangaugeII that can be calibrated to give true MPG indication. I use my programer to give me max HP with low turbo pressure enough to haul the load.
The economy comes by observing the driving habits, and knowing what your truck can do at different settings and speeds. My trucks is down to 8MPG stock hauling my heavy RV, but programed it realy goes up, and the load disapears.
So for me the best investment has been the scangaugeII that has been developped for MPG improvements.
You have to note that any boost above 10PSI, towing or not, realy robs your wallet.
