Nothing beats having a fresh water rinse after a salt water session. I recently added a new shower to my van, and it is great, It is also cheap and easy to set up. We looked at the different systems available, and have been experimenting with heavy duty water pumps for years in our school vans, and this is the best solution we have found for personal use. All you need is a 12 volt shower/pump, that plugs into a standard cigarette lighter. The water container we recommend is a 7 gallon, which is good for several days of normal use. You can have this shower up and running in a few minutes.
The shower stores neatly away so it is ready for use. We put ours in the back door to keep it handy. We use the shower outside the back door with the doors 3/4 closed to keep the water out. There is a suction cup attachment that you can put on any window or smooth surface on your vehicle.
If you want to set up one of these use the links below. It will cost you about 40 dollars for both of these items. and it usually ships out in a few days.
(Next we are adding a step to keep our feet clean as we shower on the red dirt). Stay tuned for more updates.
