The Artisan
Adventurer
here is another one that is a clean design with amenities. Maybe a mix of yours and this.My thoughts too! It doesn't have to be super fancy. Just a space to slide in the Porta-Potti, a space to safely put a stove (venting & fireproof) and a space for an ARB fridge or equivalent.
