I will tell you that when you are standing on your head trying to get one hand back there (and then add a second little person later on to help crimp), the more space the better.
I didn't fully appreciate how confined that area is until this morning. I had my mat out and was washing and vacuuming the area and I could barely even reach the aluminum front panel. To think that you also reached behind it to grab wires...all I can say is WOW.
