I just got finished with a bunch of modifications to it and got it back from being blasted and painted Thursday. I'm going to take some new pics this afternoon and I'll post them for ideas.
I also still have a four compartment dogbox that I built to sit on the front of my old trailer which might work good for you if interested. (Cheap, too!)
