I use milk crates which are zip tied to the racks. I have put my bait bucket, the Vex and another 5 gallon bucket to hold a skimmer, jig rods and tackle. The buckets and milk crates are sturdy, light weight and weatherproof. They also have plenty of ability to attach fasteners to keep your stuff secure. With a little creativity you can customize your storage pretty easily. This is also low budget so you can save money for stuff that's actually gonna put more fish on the ice.
Milk crates is one way I was thinking of using and add plywood bottom and sides to mount my auger on and keep the crates together. Did you use 2 or 3. I was thinking 3 but have not dug mine out of the barn yet to see how they fit. I was also thinking of using 1/2 ply to make a box and section it off for 1# propane tanks the vex and gas can so they don't bounce all over the place. I think the plywood would keep things in there place better then the crates would. U could also put a lid on it to lock the stuff up when at bait store or gas station.
