The best brand on the market. https://www.thetford.com/product/porta-potti-365/ https://www.youtube.com/watch?v=ty5K7Vj-yCQ Very hard to find in good working condition. Cleaned, sterilized and ready to use. Only selling because we bought a motorhome. Quick sale, absolute bargain only $50. First come first served, no holds. Less than a quarter of the new price: https://www.amazon.ca/Porta-Potti-Thetford-92820-Healthcare/dp/B07CHVQ3RM Thanks
