Thanks so much Bob for taking the time to snap the photo for me. It is worth a 1000 words. lol.
It looks like there is an opening below the tanks in the plate steel. It also looks like the tanks have been mounted on a raised pedestal. I had to do this same mod myself. I just used pressure treated blocks to raise it up so that I could mount the outerplate. Interesting. I think I am beginning to understand.
If anyone has a picture of an equalizer hitch mounted, that would be ideal.
Thanks again Bob.
