Am considering living in car but…(need your advice pls)

Hey I am considering living in my car, I’m getting sick of paying rent and need to save money, I can use my gym membership for showers or if temperature is too extreme, I can buy a storage space for any extra stuff, but where could I store my food and power my air fryer at? I’ve been thinking about a commercial kitchen? And no I won’t be buying any generator or anything of that sort I don’t have much space in my car for that, anyone have any solutions to keeping food refrigerated and having a place to plug in an air fryer or microwave ? Thanks
