It is hard to know how many DC amphours you use with your setup, so I will give you my standard advice in this situation:
Get a shunt based battery monitor, either QWORK($35), Renogy ($80) or Victron (up to $200). As the price goes up so do the bells and whistles, but the QWORK works fine for me.
With the monitor you can find out exactly how many amphours you use in a day and then plan your recharging sources accordingly.
FWIW, I use 25-30 amphours daily, except if I run the furnace for an hour or so in the morning to warm up, I use 5-10 Ah more. I do have an absorption fridge which uses very little DC. I can camp for 3-4 nights without recharging my 200 Ahs of AGMs. The DC compressor fridge uses at least 50 Ah more each day.
