Which 4X4 truck will give me the better fuel efficiency when towing a 5000 loaded TT - Chevy 5.3 V8 EcoTec; Ford F-150 5.0 V8; Ford F-150 3.5 V6 with EcoBoost?
I agree with FordLover. The difference in fuel cost between any of them is insignificant compared to other factors about why you like one over the next.
