The manual has some info about storing. If you are already two months in, sounds like you are just wondering what to expect when you get back. If you didn't disconnect the battery or set the extended storage switch (see manual) the battery will likely be dead. Six months is a long time for gas to sit around if it has not been treated. Your tires might be flat spotted etc. etc. Just be aware when you get back that you shouldn't just fire it up and expect all to be sweetness and light. Do a little maintenance before you road trip it.
