Good tip on sanitizing the water lines and fixtures. Just a thought, wouldn’t the alcohol content of the RV antifreeze do the same thing? I believe it is strong enough to be flammable.
For prolonged storage in summer, the bleach tip is a good idea.

Great tips Ray.

We still need to cover our appliance vents to keep the bugs out.  We also keep some mouse traps set to catch the little critters before they nest and rip up the place.  That also forces us to check on her regularly!

Thanks again.
