My 2017 Titan XD 5.0 Cummins diesel has a 26 gallon tank that is too small for long hauls. I tow a 4000# single axle trailer with this on occasion. I am not dissatisfied with the overall fuel consumption but would like a larger fuel tank to replace the original. Do not want an in the bed tank as I carry lots of gear for camping, hunting, fishing and more. Has anyone replaced their tank in an XD? looking for input, manufacturers, recomedations and whatever may be pertinent to this request. Thanks in advance. MTG
