Prepare for long generator run times to care for the batteries if longevity might be a concern. Solar will help but won't do much on cloudy/ rainy days or the shoulder seasons.
I fulltime and boondock continously. From my experience living like I'm on hookups using microwave whenever I want, make a couple pots of coffee daily, charge phone/ tablets/ laptops, watch tv/ dvds for hours if we want, have the furnace going and any other appliances in the 5th wheel and inverter on 24/7. With my system (see sig) during spring, summer,late fall we'll average 35% +/- DOD or 175ah daily. Late fall, winter with shorter day light hours for solar DOD goes up to 45% +/- or 225ah daily. Just to give an idea, if you're more of a minimalist or conserve more you can certainly get by on less. ;)
