Last deployment I went on, I filled the gas tank, I put the car under a cover, slapped a battery tender on her, and put the winter rims/tires on. When I got home after 6 months, she fired right up, and I had no fuel issues, battery issues, tire or suspension issues, paint was perfect, car purred like a kitten... I think there are some folks that recommend more, but mine was fine.
