Thanks to everyone in the vehicle room for your suggestions.
This is my new 2010 F-150. It has the 5.4L V8 engine. Basically the same thing I had except 10 years newer, (193,000) less miles, and a crew cab instead of the supercab. Ten years ago I remember thinking (that back seat is pleanty big enough for car seats). Now my kids are 8 and 9 and they were very cramped. In addition the older supercab didn't have head rests in the back, the crew cab does. It also has side airbags.
My first visit to a dealer resulted in a 4,300.00 trade in amount for my old truck (pictured to the right). Edmunds has my truck listed as being worth about 3,400.00 (trade in). My second trip to a different dealer resulted in a trade in of 5,500.00 (same amount for the new truck). My 3rd trip to the second dealer saw a trade in of 6,000.00. My fourth trip resulted in a trade in of 7,800.00 that sealed the deal and made me very happy. Amazing how much things can vary from one dealer to another. It will be nice hauling my camper and kids to the Smokies in June and then to idaho to hunt bear.
