My wife and i are trying to decide if it makes sense for us to get a second car. I am blind so my wife is the only driver. We currently have a 2007 Dodge Ram 3500 6.7L CTD 4x4 pickup that we need to tow our 12000lb + 5th wheel trailer. With diesel fuel costing nearly $4 a gallon and this truck getting around 14 mpg it's pretty expensive daily driver. We are spending about $4000 a year in fuel. So the question is would it make sense to get a second car that gets good fuel mileage ( 30 mpg ) ? My first thought is the cost of owning the second car would be more than we would save in fuel. My friend says we would save money because the truck would last longer and not have to be repaired or maintained as often. What do you think?
