Here's what we did when we were looking for a DRW. They are very rare here. We went to several Dodge dealers in the area and got some price quotes for what we wanted. We then went to our local small town dealer and talked to them.
DH did the research about where DRWs were located (from the Dodge website)in the state and told the dealer about it. The dealer made a deal with the other dealer. He traded a vehicle he had on the lot for our current DRW.
Just a thought on how you might find the exact truck you want and get a great price. Our dealer gave us the best price (basically matching the lowest quote) to keep our business, plus we got $7k in discounts.
