Automotive vs. RV antifreeze
Can I use regular automotive antifreeze in the black and gray water tanks and sink traps or must I use the RV antifreeze? I am in NE AR and only blow out the water lines to winterize our MH.

Grandpere.. Perhaps you have a different supplier of RV type antifreeze than the rest of us. All rv type that I have seen is sold as UN diluted and rated as
-50 or -20 . so using 2 cups or so in each trap will give you adequate protection. A gallon might last you 2 or 3 years . Try sourcing your purchase at home improvement stores, hardware stores, convenience stores and the usual wal Mart and K mart . Good luck . BTW around my neck of the woods the RV stuff
is about 4 bucks a gal
