We really like that model, too! Almost bought one on two different occasions, as a trade up from what we have now (see signature). In one case, we couldn't agree on a price; The other one, the unit (40G) was just too old, worn for our liking. I still look occasionally, but for most part have decided to stick with what we have.
We found that this particular model/floorplan is pretty popular and in high demand, especially good quality used units. There's not many on RV trader, and when they do go on there, they don't last long. Dealer told me that when he gets those units in on trade, he usually has them sold before they even hit the sales floor or got advertised anywhere.
That being the case, I would suggest contacting a few dealers, let them know what you are looking for, see if they will contact you if they come into one of these 40G units. That may give you a better chance of finding one. That is how we found one that we almost bought.
Also, will tell you from the research we did on these, that the year models you are talking about, (up through 2011) we specifically avoided. We didn't want anything from Fleetwood made before 2012 for various reasons. For this particular unit, one reason was that before I believe it was 2012, they used a different engine that seemed very underpowered for this size coach. Other reason was that anything older than 2012, you get into units that were built during the time Fleetwood was in the middle of some major re-organization, and they built their fair share of 'lemons' during that time period. If at all possible, I'd try to get into a 2012 or newer unit if you can.
