Since I've installed a LifePO4 battery and there was 2 battery vents, I replaced one with the following mod. A starlink port on the outside of my camper. It's an exact replacement for the chrome vent.
I had to have it made but could get more made for about $30. Waiting to see if I can get white that'll blend in a bit more. It has the mini port and you still have to have a way to properly power the port via 12V.
