Thanks. I plan on filling the bottom shelf with frozen water bottles to help if there is a power outage

It's better to distribute them throughout.
Also, keep in mind that meats and other products generally thaw before water. Plain frozen water will keep the contents cool but not frozen.
If you want something to keep it frozen 19.7 parts potassium chloride to 80.3 parts pure water (by weight) makes a solution that freezes/thaws around 10 degrees. We've used this solution in Gatorade bottles to keep breastmilk frozen in a cooler for 36 hrs on a roadtrip. I used to have a thread here but it got archived and I can't locate it in the archives anymore so I guess it got deleted permanently. These bottles are pretty much our go-to ice packs for coolers now unless the contents are sensitive to freezing, it will freeze things that aren't frozen...
Oh, ETA, the way I fill my freezer. Buy land, buy fence, buy cows, breed cows, finish the steers and sell (or keep) the heifers. When the freezer gets low the finished steer goes in the freezer. Profit!
