I have a 2012 3008 and have no whistling problem while towing, the TT is very quiet while underway and tows very well.
Reflecting back on a summer of ownership I have to say how pleased I am. I've spent a lot of time camping and while there were a few small repairs that needed to be made (there are always small repairs), overall I've been impressed with the build quality.
I have the awning that covers both doors and it's been super, just be sure to pay attention to rain and be sure it dumps properly. These enormous awnings can hold a lot of water and the weight can be easily too much.
As for the layout, well, it was the reason I selected this model. It's the best execution of the front kitchen RV layout I've seen. Perhaps the folks that had it originally need more bed space. This truly isn't a layout for a family.
