Best RV Antifreeze for Home Use in Interior AK

I use this -100F RV antifreeze consistently after I shower in rural Alaska to keep the drain from freezing. In our temps -50F freezes but not this product.

Great for RV winterization

This is the only antifreeze I use on my small RV. I also use it in frigid weather to keep my house drains from freezing. Don't by the cheaper stuff. You get what you pay for.
