First of all, congrats on your purchase. I think it's awesome that you're getting one.
Not to hijack your thread, but I do have a question. Is this a truck that the dealer already had on order and he told you it would arrive mid September? If you ordered it seems odd that you would be getting a 12. I ordered my FX4 three weeks ago and it will be a 13.
Seems like there would be lots of upgrades to take advantage of with a 13 right now.
