Sup guys, I am new here, and I'm exploring the option of a Subaru as a hunting/fishing/ backcountry vehicle, as an alternative to a truck/SUV. I'm really interested in better fuel economy. My current full size truck gets approx. 15mpg.. I've found a really nice, stock 2002 Forester, its rated for 19city 25hwy. If one were to put, say a 2" lift, some BFG ATs or MTs, what kind of gas mileage would be realistic?
