Hmmm, the writeup sounds like this could be the 41' that Tom had. But if so then it has been repainted at least the stripes. I've seen Tom's 41' when he was working on it and was very impressed. Don't know what it went through since he sold it. If you're interested you should talk to Tom.
The 4' difference will be easier to maneuver and allow you to fit in more campsites than a 45'. There also didn't seem to be much difference inside between it and his 45'. Newell took a few inches here and there to shorten it. But you do lose a few feet of basement storage.
Another consideration is the white paint will be MUCH easier to keep cool inside than a dark color.
