It is illegal to dump automotive antifreeze down a drain in many municipalities. It mucks up the sewage treatment plant somehow. I can imagine that in a campground with its own treatment plant, you would be even less popular. As you noted, there are environmental concerns.

The TM manual says (winterizing) ; "Antifreeze may be added to the sink and tub drains to keep the drains in working condition ..."
I'm pretty sure they meant non-toxic RV antifreeze.
