The back of the box, and panel were covered in black carpet. I sell electronics and I always have samples in the back of the truck, never had a problem with anything getting wet. I can snap a few pictures of it this weekend, and post some dimensions, I am out on the road, and will not be home until sunday, so I will post them then.
I am in the process of selling the entire system to a member, and I think I am actually going to have to put it on a pallet and ship it freight.
