This is how I store and transport my wedding cakes until they are put on display. I can’t take credit for this, I saw it on the Ace of Cakes years ago. This plastic container of holding a 4 tier cake with a 15 inch base cake drum. A non-skid pad (a piece of shelf liner from the dollar store) is placed between the cake drum and the lid of the container. I turned the container upside down because it is wider that way. There are handles which makes carrying such a heavy load more secure. The transparency of the container lets everyone see what you are carrying.
I hope this helps,
