Last time we were camping, I saw a couple with an Aliner. I was walking to the dumsters with our trash and saw the lady inside doing dishes at the sink. They had a couple of those blue water totes outside with the pipe draining into one of them. It was overflowing. After my 15 minute trek to the dumsters, I saw her and her husband coming from the bath house with a wagon and two of those containers in it. I assumed that they pulled them up to the bathohouse where there is a dish washing sink and dumped them there. I don't think their Aliner had a bathroom, but itmakes sense that what they had in the totes was nothing more than what they would have had if they washed their dishes at the provided sink.
