Blue Knight, I never answered your question: How does one get that big of a sump underneath the tank? Well, not easy, tell you that much. The way I built the stand, I have approximately 21 inches in width that I have clearence for. The sump is 19 inches wide. Instead of placing the stand first, I placed the sump first and I am going to lay the stand over the top of the sump. The stand has no cross braces on the bottom.
It seems like no one wants to help out because of the holidays. So, doesn't look like I'm going to get my aquarium moved until after Christmas.
