One thing that most people don't consider is fuel range stress. I have a 2014 Cummins Ram 2500 and an overweight LaCrosse 329 TT and after about 175 miles I start getting fuel anxiety. I know that I can always find fuel, but unless it is a full blown truck stop it is a******shoot whether or not I can get to the pumps. At least with a diesel I can easily add an in-bed auxiliary tank and have one less thing to worry about. Before anyone chimes in that they have to stop that often for bathroom and coffee breaks, I do travel with wife, kids, and dogs and someone ALWAYS has to go. It is just so much easier to find a place for a quick stop (and better coffee) than a crowded gas station. With a gas truck the only option is replacing the stock tank with one that is a little bigger for a lot more money or even carrying a bunch of jerry cans in the back - not my favorite thing to do.
