Hi Everyone

I am a new member of the jimny tribe and I am overwhelmed with all the possible modifications and accessories that lay before me. That being said my question is this: I want to run very little off of any power from the vehicle, dual battery or otherwise. I don't want to install a fridge (too much space) nor run lights if the vehicle is not running (the whole point of camping is to get away from the lights as much as possible). All I want to install is one light bar for extra visibility whilst driving for the sake of safety and two anderson plugs for a compressor. Can I run all of this from the main battery if the vehicle is running? Are there any other critical powered components/options I am overlooking? Main goal is to use the vehicle for "light" overlanding. Probably 1 week maximum.

Would appreciate any and all feedback.
