My wife makes all natural soaps and lip balms - she sells them and makes just enough to support her hobby (and buy a cappuccino). As we haven't begun full-timing yet (we will be jumping into that in a couple of weeks) I'm not sure how well it will work in an RV. She will likely do most of the work outside the trailer because of the gasses put out from the Lye. I just hope we have enough room for the gallons of oil she uses to make them.
