we have no need for anything besides our 12v battery
we have a radio, no dvd no dvr no water pump our needs are small.
we camped for 3 weeks well we boondocked and when we got home our battery
was still at 12vs.
if we do stay in a campground we stay in basic with or near the tents we like it there.
we spend our time outside enjoying the outdoors no a/c either
