I found this cool portable shower that I use for just about everything. it plugs into your cigarette lighter and you can use it to clean up, take a shower, wash your engine, clean your surfboard, clean your dog... all kinds of things. I got of them because it was just too good to pass up. You can get it at http://bigkahunashowers.com or http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=52484&item=5173870081&rd=1

I use it ALOT

so you just put the pump into the lake/cooler with water/bucket and that's where it gets its water from and the water runs through the Kahuna which has got a water reservoir. Trying to picture it, since the link 'see it in action' doesn't work

Thanks
