We'll be in the RV this winter. We have an outhouse, but it sure would be nice to have a composting toilet IN the RV for those cold days. The outhouse is very close to the RV's summer spot, but will not be so close to the RV winter spot. It'd be nice to have a bucket or something under the RV that we'd remove from outside. I know to have it compost nicely you want little to no water. The RV toilet "funnel" is pretty narrow and depends on water to clean solids off the sides. So getting rid of the "funnel" and not letting a lot of cold air in here is what I'm wondering about. Anyone do this?
