Well, I own a 2022 MME er with 45K and a 2023 Lightning er with 15K on it and I charge both of them to 100% every time. At any given moment, I need to jump in and drive 200 plus miles without putting much thought into it, so I need the 300 mile range available, otherwise the vehicle is useless...
I installed a 100 amp sub panel in the garage and added a Nema 14-50 plug right beside the panel just to have it. I since got a second electric car and had to use the plug for a couple months till the second charger was installed.
