I thought I might add a second AGM battery to my new to me Hawk. I've researched wiring two 12v batteries in series and it is pretty straightforward, so I don't see any reason not to add a second battery. Are there any issues that I should be aware of? E.g., would the alternator not charge this many batteries, does it put too much into the camper's system, or??? Thanks for the help.
