"Good idea. But instead of only keeping 2 e-chests, you should keep one full stack. Here, take these for personal use, so that you can use the 27 stacks in the Shulker as obsidian reserves for building."
*TRD420 tosses RPM another stack of Ender Chests, one that's not a Shulker Box filled with them*
"In case you don't know, the inventory of your e-chest is like the Cloud. It's private to you, and can be accessed by opening any e-chest on the server, no matter where you are. You could put all your items in an e-chest at spawn, besides one spare e-chest, then go into the Nether and go all the way to the Nether World Border and place down your spare e-chest, and it would still have the same items, even across different dimensions. Pretty handy."
