A friend did the Alaska trip with a shortbed Duramax (26 gallon tank) and never had any issues with low fuel, though he did take two 5 gallon cans.
Titan Tank has a replacement tank - that's the best option to go, that way you aren't taking up space in the truck bed with an aux fuel tank.
Is your truck "NEW", as in a 2017 model year? Or a "new to you" previous model year truck?
2017 has nothing with a 26 gallon tank, per the specs i screenshotted below:
My truck is "New to Anyone," but it is a 2016 model. The new capacity looks great. There were some aspects of the 17 that I liked, but I chose the 16 since 1) got a better deal, 2) the 16's are somewhat lower in height, 3) suspicious of a first year model, 4) not sure that I wanted an aluminum vehicle.
