Living full time in a RV, we don't have the space (or need) for a five gallon bucket of anything, but we do like to repackage stuff into plastic, preferring square shapes for ease of placement. We have had great luck with Wallyworld and/or grocery store containers, preferring Rubbermade if we can get it. For smaller containers we clean and use things like peanutbutter jars, Rolaids bottles, etc...
