I *can* remove the tank, but it's tricky and heavy. Likely I will do most of my build in my shop and then transfer in by pieces.
Then it's a lot of running in and out and around to see how things look. That's where Homo sapiens comes in. Handy when needed to lift awkward heavy things, construction minded, and good to bounce ideas off of even though I usually end up doing things my way regardless. Challenging but worth it. Have found a warm house and plenty of the right food keeps him subdued...
