I have a 2016 C-Max Hybrid SEL. I bought a tent extension that slips over the opened tailgate - which I have yet to use. Therefore my tailgate stays open 24 hrs. After a while I see that all the lights eventually go out. My question is ... is there still a drain on my battery and will it be dead in the morning? Or should I leave the ignition ON and the engine will automatically kick on when the battery is low albeit all night long which seems like a pain and will probably keep me awake! What should I do ...?? THANKS from a 73 yr old widow who still loves car camping.
