Storing With or Without Full Gas Tank

[rookie_rv]

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 ran as well as on board generator to get additive throughout the system.

Thank you in advance!

Fill it, no concerns of condensation, leave it low, then have to treat it for condensation.
Either way, you pay upfront for the fuel or treatment.
Leave untreated you risk condensation and degradation of the fuel quality. Is treated fuel better than untreated? Whats the answer when it hits your engine?

Think of fuel as a shelf life commodity -which it is, as an expiry date commodity if not HANDLED and used by date does diminish its quality
Extending fuels quality viability does make you think.
In a totally contained system without degrade everyone else is amenable and excited at the prospect.of good fuel forever

I fill it full when I come back every time.

For a month, nothing need be done beyond storing it with a full tank. For longer term storage, add fuel stabilizer to the full tank and run the engines as you described.
