What is the purpose of having dual tanks?
Why not have one 34 gallon tank if you want that much gas? I have my theories, but I wantto see what y'all come up with.

The purpose is so that you have more gas without having to fill up one large tank. Or exactly like stated above. I use my front tank for extra gas incase i run out or somehow need it. Plus, one 34.7 Gal tank would take up enormous amount of space under your truck.

Ya, it's also to keep truck bodies standardized; it lowers cost of production.
And yes, I too have discovered that it's handy to have two tanks. I feel less worried about running out of gas when I know I have at least a quarter tank in the other one.

Re: What is the purpose of having dual tanks?
The sole reason is packaging. Truck owners demand (expect) a certain range before fueling. In order to attain that range, a given amount of fuel is needed (25-35 gallons) With the necessity of an exhaust system, precious little space is left inside the frame for a single large fuel tank, so two are used instead. It also helps maintain the vahicle's center-of-mass better than a single huge rear-mounted tank, which is possible, but then you lose the spare tire spot.

It is an extra "cool" option that they can get a bunch of money for.. I have had a couple of Dodges, one with a 30 gallon tank and another with a 42 gallon tank, both look VERY similar from below, the tanks are very close in size.
The main reason is that larger trucks - many 350's and other makes of 1 ton trucks, have dual tanks so that you don't have to stop when hauling trailers on long trips. Heck we used to have a silverado dually with two 40 gallon tanks in the truck and a 100 gallon added to the bed. This allowed us to tow the horse trailer a long ways without stopping for gas.. I had a F150 with the dual 17.5 gallon tanks, always thought is was silly. just my 2 cents worth

ModMech: that was what I was trying to get at; thanks for elaborating.
As far as it being silly... I don't know, as I said, I feel more comfortable looking at my gas gauge knowing that if I run out, I have some left in the other tank. I (unfortunately) have not had the chance to take it out on a long trip. Maybe this summer...
