You'd better work some serious hours, between saving for a SUV, paying for insurance, gas, etc, etc, etc. you'll be looking at probably an EASY $8,000 or $9,000 your first year. That's figuring on $5,000 for the truck, $150 a month insurance, $50 a month for gas, plus tires, maintenance, incidental repairs, etc. Owning a vehicle is NOT cheap. It sucks a lot of my income, & I can pretty much bet I'm making more than you will be.
Congrats if you can pull it off, but you gotta look at reality.
