I drove a car this year for the first time but didnt do anything different then any other year. Simply skin, quarter, and cut off any remaining meat then put it all in coolers or even the plastic tubs from walmart if your local climate allows it. This is all done in the evening after the hunt so i dont waste any hunting time. After getting home, debone everything, freeze the roasts and loins, throw the stew/burger meat in the fridge and make burger sometime the next week. This works best for me as i drive 300+ miles to deer camp, twice (illinois's seperate seasons, whole seperate topic/rant).
Good luck
