Is it worth the extra money for the 6.2 liter motor? I am looking at new trucks and a couple have the 6.2 liter. I am mainly going to be using the truck to pull the boat. Well at least 60% of its use for now will be pulling the boat. Should I forget about it and just get the 5.3 liter or should I really consider the 6.2? Gas milege isn't really that big of a deal in the decision since I have a company truck to use for pretty much everything else.
