We camp a lot in the summer. Have a 20 foot travel trailer, but it has a 55gal fresh water tank. NICE size tank for a small trailer and only wife, me and a 9yr old. We love to conserve as much water as possible so we can take nice showers every day.! I get mighty filthy and stinky riding the dirt bike all day. We use paper plates for eating. We have several dozen forks, knife, spoons. We use them once, than toss them in the "dirty dishes bag". Brush teeth outside the trailer using bottled water. Spit in the camp fire. any plastic bowls or plates we use, we use once. Clear the plate in the fire, put in the dirty dishes bag. Cast iron gets cleaned after use using.. well, its cast iron. Wipe clean. Get home and put all the silverware in the dishwasher along with any pots/ pans that need it. Put back in trailer. Walla, lots of water saved!!!
