Obviously the sink is tiny and not good for more than brushing your teeth. I also do not have a hot water heater. The last two times we've camped we resorted to heating water in our 12 cup coffee maker, washing the dishes outside in a full-size dish pan and rinsing in a 4 qt pot filled with more hot water. We then hand dry the dishes and hope the towels dry by the next meal. There's gotta be a better way!
