As long as you don't have plain water for coolant/washer fluid you don't need to do anything. Chains are probably overkill for most roads, but snows are a good idea/required on some roads. Also drygas "iso", which is mostly isopropyl alcohol (IPA), does not prevent your gas from "gelling". Gasoline will not do this. IPA is used to increase the solubility of water in gasoline (not normally miscible) in order to remove residual water sitting in the bottom of your gas tank. You don't need it.
