I don't have. 30 Mk 1 but a Landfall 38 and I will be switching to a Nature's Head composting toilet very soon. You can completely eliminate the holding tank, all the smelly plumbing, and be zero discharge. It seems like a "no brainier" decision to me. The cost is about $1,000 but you save future pump out costs.
