I have 4 8d batteries. I had a propane fridge too but put the samsung RF197 in. I had three batteries before but pulling the propane tank made room for at least 2 though I only put one in. I can go all night and it charges right up with morning coffee. I have two Cpaps that run all night and they take power as does my office equipment. If i boondocked more often I would put solar on. I had that on one coach but decided that running the generator in the shade is easier and the mountains where I live has lots of trees. No issues and even pulled the stove and put in an induction stove.
