GMC 5.3 or 6.2 Liter Engine?
Hi everyone, I am considering trading my Chevy Diesel for a 2014 GMC Gas. I no longer need a Diesel as we tow a 25 foot Travel Trailer rather than a Fifth Wheel. I have an option of 5.3 or a 6.2 Liter...

The only trouble with the "movie trailer" is the lack of using facts about mileage. In the real world, the 6.2L is getting the same and in many cases, better mileage than the 5.3L, so mileage is NOT a factor.
Gm is claiming a best in class 23mpg for the new 5.3, I see no such claims for the 6.2, perhaps you can provide some proof?
