Should I get a new Tow Vehicle or a Bigger Gas Tank?

Diesel provides greater fuel economy but the total cost of ownership is double that of a gas powered vehicle.

After owning both I fail to see the dbl the cost. A couple fuel filters is all thats different. The better mpg's of a diesel will cover that.
Oil changes on new diesels are longer than gas. Syn oil for gas trucks is not cheap.

All other maintenance is the same.
