You must live somewhere nice to be just winterizing now! -15 windchill this morning here. It feels like the middle of January already. Maybe that means spring will be here in February this year.
That's a good idea especially for times like now when you don't want to put water in your camper. With compressed air all you need is good ear for big leaks or a bottle of gas leak detecting soap for the small leaks. like you said just don't over-pressurized 30 to 60 psi should be enough.
Has your Aviator been good so far?
