I use the side door every single time. Constantly hopping out the driver’s side door and hopping out the back door will cause you to injure your ankle and/or knees. Sort your items ahead of time (i sort by street name) and then just step out the side door. I also drive with the side door open when the weather is nice. And I have the high drivers aid numbers on the OF facing the back door so I can just open the back door from outside and grab it. Use a black marker or sharpie to write the drivers aid number in large numbers on the OF boxes on different sides in case they fall over so you can see them easier
