For long trips, I place my travel Berkey in the sink of my 17B, anchored to the faucet with a bungee cord and surrounded by the bubbly sheets Amazon uses to pack most everything. I take special care to protect the plastic water spout, and filling the base half full helps to keep it from bouncing around. So far, so good!
For short trips, I fill these water storage cubes and leave the Berkey at home.
Love my little Berkey! And my little RV!
