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.

No! Auto antifreeze is toxic. RV antifreeze is designed for the water lines and is non-toxic. Never use automotive antifreeze in your water lines.
