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

I guess it's possible, my Dodge uses fuel filter that my Hyundai doesn't. The tires are much bigger, the air filter is more costly, differential fluid that the car doesn't have. Brakes are a bit higher,

So my annual maintenance for the Hyundai is about $35, and the Dodge is about double that at about $85. So yeah, maintenance costs are about double.
