Returning from a short 4 month deployment in a few days, I left the keys to my 6 with a friend, however I doubt it's been reliably started up. Expecting the worst, what recommendations could you guys provide? I'm planning on charging the battery before starting. Not worried about flat spots, as new tires are the first thing on my list. I changed the oil just before leaving, added stabilizer to the fuel. Left a dehumidifier inside(Florida), again, I doubt it's been reliably emptied. Any crucial information I should know before warming it back up? I appreciate any and all help in advance.
