GMC 6.2 10 speed Max tow package (3.42 gears) = 9.8 on 91 octane
Ram 5.7e 8 speed ORG w/ air (392 gears) = 9.2 on 87 octane
F150 3.5eb 10 speed (3.31 gears) = 8.7 on 87 octane
This is relatively consistent with The Car Guide (canada) results, where the Ram won in towing MPG (possibly due to the use of different fuel)

Explain to me again, why the ol' 5.7 is such an outdated, poor performing engine?
Edit: Discovered TFL used 91 in the GMC only, and 87 is the Ram and Ford, per TFL response (post #42 of linked thread below)
