Here is the dual 6v battery box

I know I posted some of this stuff in the other thread you posted on, but I wanted to post it here too for future viewers.

I included a picture of how the lumber is attached. That photo is taken from under the tongue.

Thanks Logan. Seeing pictures of the different methods that others have done is very helpful.
