We just returned from a 2,200+ mile trip, topped off 2 miles from the house and put it away for the season. Unless something changes it won't come out of the garage for around 7 months. I have zero concern about the diesel going bad.
I've owned our Journey since '17 and never even heard of problems with water or algae after storage.
