Just got back from desert trip(San Diego to Ocotillo-District 38 area). MPG same trip last year with stock truck,towing toyhauler, was 10.2 mpg. Edge/Att set at 1/5 and 35" tires DIC read 13.2 mpg uncorrected for tires. Attitude set to warn when hit 70mph(corrected for tire size), speedo reads 62mph. Toyhauler was fully loaded: 4 Dirtbikes, 100gallons of H2O, etc.etc. Needless to say I'm extremely pleased!!Anyone else notice same improvement after such mods? Truck has 18,000 miles on 'er.
