Looking for Battery & Solar sizing spreadsheet

My 6-something cu.ft Norwarm draws 12-13 AH when it's hot. DC circuit of propane fridge is one of the biggest 12V draws. Exhaust fans running 12-14 hrs on a hot day draw something too, but then you spend more time outside and day is longer in summer, so you burn the lights less. Yeah, can be more than 40 AH total for 12V loads if you are like Mr Trump and spend more than you have :)
