We are planning to put a Nature's Head into our Airstream when we get it. Met a gentleman last weekend at Overland Expo East who had one in his Tiger overland vehicle. He was having odor problems with it, but readily admitted that he had not properly moistened his peat moss before putting it in the mixing tank. Proper moisture levels are important.
We are going to use coconut coir as our composting medium instead of peat moss because the peat moss bogs are being decimated and habitats are being destroyed.
Check out "Gone with the Wynns" videos on their composting toilet. Quite educational and fun.
May your days be filled with love and laughter.
