So I bought a brand new Coachmen Clipper February of 2018. Camped all last season using electric hookups. Earlier this winter, I decided I should check the batter voltage on the battery. It was dead. Now, I'm not talking about, "hey my battery's voltage is 11.8 and it's dead." The voltage was reading 0.8! I didn't even know it could get that low. So I charged it back up with a trickle charger until it was fully charged. It has been sitting "stable" for roughly 6 weeks now since I charged it up (maybe 8 weeks). I checked the voltage again tonight and it's reading 2.17 volts. The factory installed a Deka Marine/RV deep cycle starting battery. I thought I read on here that 12v starting batteries were not good? Is there that much of a constant pull on the battery that it should be totally drained that far in a matter of 6-8 weeks? That seems very crazy to me, but I am at a loss here.
