Other than making or buying a gun box, I’ve been looking for a storage container that I can put 3/4 cased shotguns in to keep dry while in the boat. Needs to be appx. 52” long. I’ve searched the likes of NuLine, Plano, Rubbermaid, Grainger, etc. to no avail. Couple years ago I found something in Wally World but decided it was going to be a little fragile. I can find good containers now up to 46” but nothing larger. Surely something is out there that will be the ticket? Appreciate y’all’s help.
