Storing With or Without Full Gas Tank
Hello, Rookie RVer here! It is best to store motor home with full tank of gas to prevent water accumulation when it will sit for a month or more? Of course there’s fuel additive added and engine ra...

Water in fuel from condensation is a bit of a myth. Ran the calculations one time on a 200gal tank (in the boat). If every last molecule of water was transferred from the air to the fuel and the air turned over 100% daily due to heating and cooling, it would amount to little more than a few drops over the course of 6 months. The ethanol should easily be able to absorb it without phase separation.
I'm firmly convinced that water in fuel is typically coming in either with the fuel or from some sort of leak. On boats, it's not uncommon for the fuel fill to be on a flat horizontal surface, so if there is a break in the seal, it could dribble in over a long period of time. Less likely with an RV and a vertical surface mount.
I will agree with putting some stabilizer in as fuel does go stale. I also like leaving the truck with only about 1/4 tank, so in the spring once it's started, first thing is to stop by and fill up with fresh fuel.
