CLM...
Welcome to iRV2!
You will find everyone here willing to help as best they can
I did a search and the only model numbers that come back associated with a 2009 Dutch Star/Dutch Aire DPs were floorplan # 4055, 4331 & 4317...which indicate to me that they are 40' and 43' floorplans. You might be able to get an idea of what these floorplans might look like if you go to
Newmar's Product page and look at the floorplans with those numbers associated with them now.
The only other thing I might suggest is to contact the dealer you might be interested in working with. They should have an idea of the available floorplans...since they are placing orders.
Good Luck in your search...and again...welcome to iRV2!
