Out houses are great for the long term, but for temporary use I bought a Reliance porta potty (bucket with toilet seat and lid) . Bought some camping toilet bags with gel inside and was amazed at how functional it was. I bought it for my little vanagon but have never had to use it. So when my drains were out of commission for three days this spring and I was unwilling to crutch out to the outhouse in the dark... Voila! The bucket was amazing, just parked it next to the toilet. I have a different version out at the cabin, without the bag- just add water and fertilize trees!
