I am seriously considering selling the '06. Its at the point now where I need to spend some money on it. Theres 155000 miles on the original transmission. We plan on doing some traveling next year. The navigation screen is permanently black now. The seat is junk. Ive fixed the wires to the rear doors 3 times now. Little tiny spots of rust here and there. Is it time to update or do I just spend 10000$ on this one. And go another 155k. If I do go for a new truck should I grab a 2012 at the end of the year or see how the 2013's are. I think the 2013 will have urea. Which doesnt really scare me. My wifes last 2 cars have had it. Any other info on the 2013. transmission. Engine. Tow packages. Thanks guys
