That's a whole lot of layout to take down and pack away. I well know the empty feeling that comes with doing that, especially if there is no future for a rebuilding anywhere in sight, which has always been the case for me when this has happened. The last time was about two decades ago, and still no place to unbox and rebuild has been found. Soooooo sad!
But, it seems that you do have a plan, and may soon have a place, so for that I am very happy for you and wish you and your future layout all the best!!!
