david, yes there is a vacuflush system on board with fresh water. the smell did not come from the head, but rather the holding tank vent, or in my case used to until i installed an in line filter. i'm pretty sure that became standard equipment in subsequent years on that boat.
it was a never ending battle to treat the holding tank waste with all kinds of chemicals and bacteria etc. the filter paid for itself the first year in not having to buy more chemicals never mind the fuss. I'm pretty sure the issue had more to do with the higher temps here than anything else.
