check out
www.carlocate.com and see what pops up. I checked a few of the states that I tried before ordering our 350. There was a dealer in Missouri that claims to have a 550 4x4 6spd/PSD, but it didn't give much other information about options or trim. They only show a posted price of just over $30K, so it must be fairly stripped, but it would probably be worth a call...
added on edit: DOH...nevermind about that one, I just looked at it again and it shows to be a regular cab. SOrry..
