Demountable camper group

The pictures above are from my internal shower setup in my Suntrekker, the container is 10 lt and would do me for 2showers or 1 plus a bit for my wife when it's Hair day
We just boil a kettle to heat, I have black taped the container to place in the sun before adding the kettle.
The shower cubicle is sealed at the base so I just reverse the flow when finished and fill the container with the used shower water for disposal.
The cubicle came with a full pole assembly but I only use the ones in the picture ( a lot less time needed) the pump is a submersible one.
I also have the black floopy shower bag for a post beach shower however you need to take the plastic tap apart and make the hole larger when it's *on* and also it helps if you make the head holes larger

Thanks for the photos.
I like this idea and the Suntrekker has a perfect roof shape for this if mounted to one side .
