My two cents worth here. Regardless of what the label says the alcohol-based is toxic. Look up wood alcohol and Gilly juice causing blindness.

I only use the alcohol-based in the drains and add it to the black tank in freezing weather. The only rubber there are the seals on the dump valves and I keep them greased with silicone.
Although harder to find I only use the propylene glycol which is non-toxic and will not harm the seals in the fresh water lines as the alcohol-based can strip away the oils in the rubber seals causing them to break down.
