Thanks everyone, I appreciate the input.
We like to camp at a couple spots that only have "Outhouse" vault toilets, better than nothing but not ideal, and one of the locations depending on where you setup you could be .5 miles away from the toilet. We also have a 2 year old that doesn't give much warning to when he has to go, so having the ability to use the bathroom in the camper is nice.
If I'm using the storage tanks I'm guessing it would be a good idea to pour some RV antifreeze in first before any water goes in to keep the section of pipe by the drain valves from freezing?
