Hi EandC,
Welcome to the Heartland Family. Your dealer should be able to furnish you with the VIN # for your newly ordered Landmark. I don't know how much information you can receive except possibly the dates it goes on line and date it comes off.,, Or if your adventurous and can travel to Elkhart, you might even get to watch it get partially built or rolled out the door if you make some calls and arrangements.
