If you can afford it go for the 5.7. if you really want to keep it forever, find a way to buy it, not lease. I really know what its like to have a vehicle you're not 100% happy with. I bought a 2005 F150 lariat supercrew totally loaded cause I got a killer deal. I was unhappy before I ever signed. It was a beatiful (imo) truck and ran and drove and rode awesome, but I just wanted a tundra. I'm glad I waited cause the 2007 is much nicer (again imo)than the 2005 I thought I wanted. You only live once man so get what you want. Good luck w/ your decision and w/ your deployment.
