Hi,
Not filling up may lead to condensation in the tank. Water in fuel is not good.
If I'm going to be storing the RV (mine is gas) I do the last two fill ups with premium. Where I live premium has no ethanol in it.
If I am traveling the last item of the day is to fill the tank. That way I can pull up stakes and get down the road in a timely manner. I often stop for breakfast after the first hour. I try to take short breaks on an hourly basis.
