I recieved a single page brochure from my dealer about a month ago. Today I recieved a marketing piece from Dodge. It's like a child's popup book, you pull on one side and a slider comes out with the 4500 info at the same time it puuls out another slider from the other side revealing the 5500's info. There isn't anything new, infact it has less info than the initial press release, but it's pretty cool none the less
