Thinking about a i-4 trail hawk. Using it to commute during the week and truck trail ride 5 or 6 weekends per summer. Lots of posts stating the I-4 is so underpowered it will get worse hwy mpg than a v-6 (I usually drive 60 miles per day, 70-75 mph). What are your thoughts. NOTE: I won't be doing any towing.
