So can I. But my generator uses 2 gallons of gas a day. (well, except for

Peak load becomes important. Then you have to manage a smaller unit by
taking things off line or making sure several things do not come on at
once. My neighbor gets by with a generator half the size of mine but
wishes he bought a bigger one.
