I drive a Dodge B250 conversion van with a 318 V8 right now and will soon be Xterrarized! Will the gas mileage be any better???? I see posts of 12 to 14mpg when towing, my van does that. It costs me roughly ten dollars an hour to drive my van on the highway when gas is 3.00/gallon (canadian) How many miles do you guys get to a tank of gas??

Thanks for the input,

Mike
