Well I cant say whether to "Flip or Keep" what I can say is if you decide to "Flip it" but are concerned about the V6 in the newer models, you are not alone. Do what I did. I bought a 2014, which is the last year the 5.4L V8 was available, I couldn't be happier. Yes it does burn more gas, but it suits my needs, It has plenty of cargo space, it has the roof rack on top for hauling larger items, and it's powerful enough to for towing my heavy trailer, or my boat, If I was only concerned about gas mileage, I would have bought a Prius. This truck has plenty of power when I need it. That's just what you get with V8 power. You don't have the delay when you punch it like you would with the V6 turbo. It takes a few seconds for the turbo to wind up before it gives you the power you need. With the V8, the instant I punch I'm literally glued to the back of my seat. Also, the other reason I chose a 2014 was to avoid the 2 piece spark plugs that Ford used in the 2005-2008 models that were prone to breaking apart when you tried to remove them.
