I had asked the same question of Sam while ours was being built. He did indicate that while you could get in touch with him to setup a tour of the factory, trying to see yours actually being built would most likely not be possible due to not knowing which specific unit would be yours. I don't want to put words in his mouth though.
We are planning on taking a tour sometime as I think it would be great to see the factory and how everything is built, I just need to find time that I can take the wife and kids so that we can all see it.
Unfortunately I'm not going to be able to make it to Goshen this year.
