Has there been a final decision on which side of the vehicle the charge port is located on the R1S? I am planning a new garage layout and I have to inform the electrician of the location of my Level 2 charger.
Not sure, but if you can't get the answer in time you can have the electrician rough-in a conduit on both sides, and then wait to pull wire and install the charger until you know for sure. Roughing in conduit in an additional location is a minor cost in the grand scheme of things.
I emailed Rivian in June with the same question. Here is their response: "As far as the charge port, it will be located on the passenger side right below/behind the headlight! Using a J1772 connector and a 40 A circuit, you can expect a full charge every morning when you plug your vehicle in before bed."
