Thank you all for your replys!
I think I am sold on the equal-i-zer, as it does seem to be a simple design and should be easy to install when I pick up the trailer. It looks to me that I would be drilling holes for the dual cam type, and I won't have my garage full of tools with me.
I think I am also sold on the Prodigy brake controller. Does anyone know where to find the factory connection for the plug in harness on 2000 GMC? I would like to find this before purchace so I know what I am up against. Also any tips on install would be appreciated.
