they have everything! Also farm and fleet or a boating store.
Farm and fleet has 65 gallon vertical water storage tanks. They are very durable and have a bulkhead on the bottom already. Could be a good option if you cannot find a barrel. I am guessing they are very similar in dimensions
Well you pinpointed me in the exact direction. I was hoping that it wouldn't be that much. I had a buddy pick up a couple for free before (lucky find). I'm still going to work that option if available. If all else fails I stick with my current 29gal acrylic water storage tank or I venture over to farm and fleet and pay the little extra money. Thanks for the find though.
