Need to add that if you want to leave the Porta Potti in the RV when not using it or the RV in the winter when it's below freezing temps outsode and no heat, pour/use windshield washer fluid with the antifreeze in the top rinse tank for your area. Our stores here sell the blue colored washer fluid in one gallon plastic bottles good to -30F usually but it never gets that cold here. Costs $1.39 a gal bottle here and we only use about 2 gal a week for the two of us. Cheap! That means that even diluted 2 or 4 to one with human liquid, it still wouldn't freeze until way below zero and then it would only get slushy at worst. Never even seen it get any slush in ours yet here in over 30 years of doing it.
