how long can one store a gas engined motorhome?

the genny carb was drained when we parked it. hope that is enough.

If you are generator equipped, I would disconnect the fuel supply to the generator (and cap it off) and run the generator until it stops. In lieu of that, Onan recommends that you heat cycle the generator on a monthly basis. (run it for +-30 minutes under moderate load)

When put to the test none of the "stabilizers" works very well. Aviation 104 has 0 ethanol and last dang near forever. Had it in my dually that was stored for 4 years with this in the tanks. New battery and it fired right up, and never missed a beat. Ethanol is the enemy, if you have to store it for long periods of time....put non ethanol fuel in the tank. It's not as good a Av gas, but it better in the long run.

hope to hear from them
thanks

Millions use Seafoam

thanks
has anyone else used seafoam?

what is seafoam and what does it definitely do?
thanks

If mine I would treat the old fuel with Seafoam according to the amount of gas in the tank... a little heavy on the Seafoam will not hurt it.
