Let the tank pulling begin, after a failed attempt at using a winch I went with the tried and true "floor jack method", worked like a champ.
Working my way down the tank breaking each area free of the foam.
Used my degree in redneck structural engineering to put this contraption together to break it completely free of the foam:

Spent a little time cutting up the deck before calling it a day. As you can see, and unfortunately for me, the bonding between the deck and potter putter so far is really good, no gaps like other people have found.
Thanks for looking!
