I think the lack of info on the Dream and my own unit is because they didn't make many of these expensive models and still don't. They concentrate production on the more affordable units that more people can afford.
We purchased a '99 Dream last fall. 100K miles. Haven't read anything negative about it and I poke around the internet a lot. It passed inspection with only a back-up light needing replaced. We had the pre-season 'physical' a couple of weeks ago with absolutely no issues.
We're still learning all the systems and haven't found anything at all lacking.
Saw one about that year an Ebay today.....Never had one but they look pretty nice. I have an older high end DP (1997)and could never afford one with all these upgrades at todays prices. But I like the looks of those American Dreams and they seem to be equipped well.
