First off sorry if this was already talked about. I did a search but didn't seem to come across the simple questions. When running a radio,cb, trail lights, and air commpressor..(not all at once) Do you need to run two batteries and an alt. that puts out more then a stock alt.? Or are you o.k. till you start getting into a winch? The trail lights are some kc 100\130w. nothing crazy like those 400,000watt hella's
