It would be nice if the floor of of the rear hold were flush with the bottom lip of the door. That would allow you to more easily slide heavy items over the lip without damaging it.
I don't carry anything in the compartment that is heavy except the battery. When I take the battery out for winter storage or changing I found that if you opened the shell and did not pull out the bed you could get more leverage. I also added a shelf so I would not have to sort through so much stuff. Very easy to make. I put a photo in tips and tricks.
