Has anyone disassembled a PCNC1100?

I am considering buying the Tormach PCNC1100 and I want to put it in my basement. To do this I will need to removed the head and column. I have been talking to the tech at Tormach and he is not saying I can't but he has some reservations. I know that the 770 is designed to come apart but I want the extra travel of the 1100. I already have a small bench mill with the travel of a 770 so there is no advantage to me getting another machine like it. The head and column are pinned so assuming everything is machined accurately, it should all go back together the same as it came apart, in theory anyway. The tech's biggest concern was tram but he admitted that he has never had one apart.

Does anyone have any experience with this and what did you run into? I am not new to the machine trade.
