Just got my this, all stock, and want to add some power for a yet to be purchased fridge and maybe some rear lights. I am not a wrench guy but the national Luna auxiliary battery setup doesn’t seems too hard- all you need to do is run the power cable to the rear cargo. Has anyone done this and made a video? Any plug and play alternatives for a simple solution. I was looking at that portable Dakota lithium setup, but not sure how you keep it charged on the road. I have researched on ih8mud but can’t find a link that keeps it basic. Thx
