Not saying it is not technically possible to increase the fuel tank size with the current vehicle design, but if I had to choose, I pick smaller fuel tank with a spare tire vs. larger fuel tank with a can of "goo" to address any flat tires (which by the way won't do a thing with a larger hole or sidewall tear...)That’s something I left out. With littles, we make more frequent stops than I normally would so it didn’t bother me on this trip, but the most we got out of it was the 359 (<20 miles to empty). I feel like that is just very average. For what is supposed to be a family hauler, road trip warrior type of vehicle, it is an area they could improve on. Just a couple more gallons in the tank should get it to a good spot.
