something we left out. your current 27 series battery might have 70 amp hours?
you already have around 1amp of electrical load in your camper without even turning on a light. its the CO and Propane detectors.
1 amp will draw your 27 series battery dead in 70 hours. But you don't want to drain a battery past 50% so every 45 hours your going to need to charge that battery.
Now during winter storage (with 0 load), I hit mine with a 15A schumacher 3 stage charger every month.
on my Wolf Creak I have AGM batteries which have less self discharge,and they should be good for 6 months without a charge (and 0 load), but I have a battery switch installed that turns off battery power to everything, but still leaves solar cells connected. Even through my classic accessories poly pro 3 cover the solar gets enough sunlight to keep the AGM's charged all winter.
