I bought fridge braces thru etrailer. They hold like milk jug or whatever u have in fridge from sliding around. They adjust using a t-nut thru your racks in fridge. Haven`t used them yet so I can say how well they work.
I keep old 6 pack cartons and have been know to keep some things in those. I switched to using the tervis cups as they are good for keeping hot stuff hot and cold stuff cold longer. They are plastic and durable. You can also get the rubber shelf anti-slip liners cheap at Wal-Mart. One time I bungeed my milk in place because my fridge was too full and I couldn't fit the milk in a good spot where it wouldn't fall. That was a pain in the rear.
We use the double refrigerator bar to hold things in place while traveling. Camco sells both the single and double bars.
I use this as well does a fair job just wish it had a way to move the rods closer to each other.
