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.

If you blow out your lines. Why not empty your holding tanks & buy a gallon of RV antifreeze is cheap . Put a small amout in your traps, Don't forget the your Trap on your close washer. AND FORGET IT. Did this for years .
