Idea,<div>right now I am using a spay pump up bottle, it is a 2 gal version, just pump it up then spray yourself down.</div><div>Will be getting a 12v bilge pump for only about $24, for space considerations, yes even in this large box truck there is not enough room, and by the way it is only 14ft box truck not the 20 ftrs.</div><div><br></div><div>Right now I just have a shower in the back, or do the wash down thing when I can not get to the gym to workout and have a shower. I will start to lay down a tarp propped up on one side and it just flows out the back under the roll up door. Yes, eco friendly soap.</div><div><br></div><div>I was looking at Canadian Tire and Coleman makes compact cube, Hot Water on demand unit for only $135, put the bilge pump one one side and have a shower on the otherside <img src="/images/boards/smilies/smile.gif" border="0" align="absmiddle"> (you will need two hoses and a tap, as the unit is very hot, so regulate with cold water) Right now I have not gone over 1 gal for any shower, with the unit set up I might, but as you can install a garden hose in place of a tap, so you save water as you only spray when needed, not let the tap run freely. I will do what someone said above, modify a plastic box with a drainage tap, then just let it run out, grey water is safe enough for the environment, especially if there is a small hole to run it into.</div>
