Sounds like a good deal. The 2008 SUT's are out already as well. The first dealer I went to had a couple of them.
The new engine and trans are great. I haven't gotten through the first tank yet and done any official mileage calculations, but the DIC is reading 15MPG average so far with less than 300 miles on it.
My 2005 I was seeing 12.5MPG with about 9000 miles on it.
Don't know for sure yet, but it looks like the new engine / trans / gearing is helping some with the mileage.
Now what are the Tree Huggers going to complain about?
