MPG Increace

pretty much yes, if your trying to get fuel mileage out of a jeep, any 4x4 or a truck then you need a car;

people who use trucks for trucks are not worried about fuel mileage, it is what it is, can't get 50 MPG from a truck

Yeah, you should see the full size Jeep forums. We get pretty giddy about 12 MPG. The Diesel conversion guys get all snooty about their mid 20 figures...

It's all relative. Funny, but relative.
