Expanded stash mod that works for vanilla (no expansions)?

Grim Dawn Modding - Discussion

Hi! I’m looking for a mod that increases the stash (smuggler) window size, so I can store more items. But it has to work for “vanilla” Grim Dawn (version 1.1.6.2) since I don’t own the expansions. All the ones I’ve tried (like Caravaner, Grim UI X-Mod, …) require the expansions.

I’d be grateful for suggestions.
