That was my thought. I hate to be the a-hole who points out the problem without having a solution, but unfortunately that's the situation.

Also, have you considered using expanding foam for insulation? I would think it would fill up odd size spaces and gaps better than rigid insulation. It will make things more air tight and therefore your refrigeration unit will be more efficient. You'll probably have to let it sit for a while in order to out gas, but nothing done right is quick.
