I ordered a 2007 4.7L double cab about a week ago and now I think I really want the 5.7L. The truck is not supposed to be assembled until the end of this month. I need convincing one way or the other can anyone help out? Also is there anyone out there that just recently ordered a tundra and still got that $1,000 trade in offer. My dealer said they couldn't accept a trade-in until my vehicle had arrived unfortunately this incentive will surely be over by then. I'm due to get the truck around mid May.
