Finally received my 2019 F-350 diesel crew cab truck. My wife and I are retired so this will be used as RV trailer hauler as we make our way across the country. My last F-350 I was able to add a Transflow 47 gal fuel tank with no problems concerning fuel gauge reset. My question is I'm purchasing a Titian 55 gal fuel tank to avoid stopping at so many gas stations pulling a 30' trailer. I was told the new 2019 F-350 trucks and diesel gauge can't be changed to read the correct " miles to empty "due to software issues is this correct and what can I do to make this work?
. Thank you Robert

 

Any suggestions on how I might recalibrate my fuel gauge to work with the Titan fuel tank?
