Hi! I'm looking to build an outdoor (enclosed in its own small shed/shelter) compost toilet on my small farm in Montana (Zone 3/4...cold & arid climate) primarily for summer use full-time by one person and also occasional event usage by 10-40 people. So, far I've been recommended both the 'Sunny John" and barrel type systems. Looking for any advice on one versus the other? And, any recommended resources on construction? Thanks in advance!
