Auxiliary Diesel Tank Gravity Feed vs. Electronic pump

Another plus of having a large in bed tank is that the truck rides much better when the tank is full, I carry 95 gal in the bed and usually try to refuel when I've used around 50-60 gal. It also saves money in that you can bypass the expensive states and fuel up in the cheaper ones. I have saved up to a dollar a gal that way, makes a big difference when you are putting in that much fuel.
