Ok looking to get inside all of the experts minds..... Rofl. I have a gang box in my pick up truck with 3 deep cycle batteries for a battery bank. Leads go inside cab to a 2000 watt inverter that i run devices for storm chasing and spotting. The system is isolated from vehicle charging system. I currently only have inverter ran to chasis ground. All radios, icom 7000 w/Texas Bug Catcher, cobra 29, Bearcat phase 1 and phase 2 scanner all run off of vehicle system. Question..... Should I run the negative termanal to chasis ground also? Ive read multiple articles and it seems that some say yes and others say no. Needing all of your experts thoughts on this idea.
