No doubt there are lots of options for water storage in vehicles. That's a good thing.

I'm not a rich man, but I find <$3/year pretty darn cheap actually to be free from concern of having water go bad, leak, forgetting to rotate or restock, etc. Especially so for family members where "set and forget preparation" is the best one can hope for.

Your mileage may vary of course... and that's just fine.



((Before someone asks since it seems important to the discussion: Case of Datrex/Mayday/et al is around $24. Split between two vehicles and over 4 years let's say... 24 /2 = 12 /4 = $3 per vehicle per year ))
