Alternative to an Airstream's quality and beautiful windows?

I watched the OP's video series on purchasing and 'attaboy for doing it. There is not a lot of video about purchasing. I listed my thoughts in the other thread in the Beginning section of the Forum about the Airstream. My only suggestion beyond that is....slow down. I don't know the OP's situation but just judging by the vids and the posts here, there needs to be some more looking.
