Keep a small waterproof tarp in your possibles bag along with your bungee cords, tow strap, gloves, pulley, shackles, tire repair kit, first aid kit, and everything else. Then if you kill a buck, you can fold the back seat up, lay out the tarp in the back and throw the deer on the tarp. You'll want to get home quickly and get the deer hung and skinned though, because that hide and tarp traps the body heat and I guess the meat could spoil.
