You should most definitely checkout High Country 4x4. More info here in this thread and my post about my interaction with them:

He's extemely knowledgeable and was very flexible during the build process when I requested a few changes and additions to what I had originally spec'd out. He even managed to track down a set of discontinued wheels that I really wanted. I spent a couple days searching for the wheels online with no luck but Brady took the time to make some calls and was able to find a brand new set of the discontinued wheels that seemed to be nonexistent. Do yourself a favor and give them a call.
Now that it's nearly 2 years after they did my build I can add that not only was the build experience itself great but they've also done an incredible job supporting any issues that have occurred over the past 2 years. I know some people here have made comments that they're a little pricey but you get what you pay for and quite honestly I don't think they're any more "pricey" than any of the other shops or dealerships. They're very good at what they do and easy to work with!
