Buffie--Emergency Essentials has a toilet seat for a 5 or 6 gallon pail for $16.95 this month. Put a heavy-duty garbage bag in it, or put a little water and Chlorox in the bottom. We used one for 3 months for night use in our tent, camping in Vermont in 2006...dumped it in the porta-toilet we had rented and placed 60 feet from our tent. I kept a gallon of water and a bottle of Chlorox in the porta to rinse the bucket when I dumped it.
