like you, with the battery in the trunk, i had drastic impacts to voltage level any time something pulled on the system (headlights, radio, brake lights, cooling fans...). i pulled the grounds at the radiator cross member, rear cross member for the battery and the alternator. i cleaned all with sandpaper and reattached. i replaced the alternator ground wire with a new one. the problem is not gone, but it has helped a bit.
have you tried running the ground from the battery back up to the engine? i may experiment with a jumper cable just to see if it makes any changes. i'd like to exhaust all my options before assuming the alternator is bad. but, the voltage does drop when the engine is warmer, thus indicating a possible bad alternator... fwiw, this is becoming a larger problem for me as the voltage drop is impacting the wolf system and causing changes in fuel mixture. it definitely means that i am getting closer to a good solid map as it is getting a lot more sensitive to small differences.
