We are using this as an outdoor shower in a fixed location. I didn't realize until I read the manual that the intake hose has a submersible pump on the end. Instead of trying to attach it to the collapsible 5 gallon container, I dropped the intake line into a 55 gallon barrel of rain water. Also, for a fixed location, you can buy the propane converter hose that lets you use a refillable tank instead of the little cans that you can't reuse. We also got the shower head. Very easy to use. Good temperature control. Easy to take off the shower head and get hot water for tea. The 6v battery can be recharged with 120v or 12v and both plugs are included so it would be easy to use this off the grid or even off the map.
