Just finalized buying a '05 35U yesterday. During the process we considered ordering with several minor option changes we liked but found out that all orders for the Adventurer line were now going to be for '06 model year. We were unable to get any information on the colors, option packages or price increase. To make a long story short, we ended up buying one off the dealers lot that we liked.
I just did a Walk-thru on a 2006 Georgetown by Forest River this afternoon, the manufacturers keep moving the next year's models up earlier and earlier. I would think that the new prices will be coming out shortly..
