I read thru much of this blog last night. These two created a Nidacore camper but also approached everything very simply. One Thing I picked up was using 4" PVC pipe as additional water storage. I'm thinking about how to use this for grey and blackwater storage in my tiny Skamper. Anyway. Thought you might find it interesting.
