RE: One night running the heater and blower
“Would it be best to get two Group 24 batteries and run them in tandem?”
Buying Group 24 batteries by anyone except those that almost always plugin isn’t a wise decision IMO.
RE: One night running the heater and blower
Should be easy to determine the amp hour draw and then your battery’s AH capacity with 50% useable. What make and model heater? 60 to 65F overnight seems warm to me, however. Dry camping is great! True freedom.
