He certainly is correct but... I do a lot of boondocking. When I'm solo, I can stay out for up to a month on my 150 gal. of fresh water, 60 gal. black and 80 gal. grey. No way that I or my coach could stay smell free w/o the incredible nearby hotspring shower and the GEO Method. I use bleach once a year and my toilet seals are 26 years old. In case you're thinking "Ah, he's just used to the stink," believe me, my wife or friends would be happy to put a clothespin on their nose to make a point.
