It seems minecart and piston structures that move don't consider inventories attached as valid unless they are vanilla chest or create crates. Would be extremely useful to be able to have Storage Drawers (that are filterable) or ender chests to be considered valid inventories.

Bump to avoid being closed. This issue seems very much relevant and actionable.

ender chests can't, as their contents are stored in player data rather than in block data. Ender chest is like thing used to access 27 hidden slots of player inventory

Ah I meant the ender chests mod ender chests, not vanilla ender chests.

iron chests chests for larger inventory also comes to mind

ah, ok... BTW, Create Integration had an ender crate, that works similar to ender chest from echest mod, but also works when mounted on conraptions
