Here is a picture of my aluminum boxes that Richard Elkins built for me. They bolted on both sides very nicely. They are waterproof and lock. I have a dry bag buggy corded to the top. In the dry bag I have my tent, sleeping bag, sleeping pad, folding chair, and folding table. All the rest of my camping stuff, clothes, food, laptop computer and a few other things easily fit into the boxes. The black bag on the back holds the stuff that I will need during the day... I leave in one week!
