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...

If you in a hilly or mountainous area the 6.2 will be excellent. But if in a more flat area the 5.3 ecotec will be better on mileage.
