Rear door ladders?

[10G]

There is a GU I see once in a while near my work with a ladder like that or similar. I like how it looks and I can see how it makes life easier to get up there.
But I personally don't like how its attached to the door, especially considering that small door is not that strong. Hung on the top, weight on the ladder wants to peel the top of the door away from the body.

Yep, I understand what you're saying. Most of the ladders I've seen bolt to the door, so you'd still have that problem A smart person would design some retractable legs that can pop out and sit on the rear step when you climb up on the ladder.

I'm thinking of mostly carrying canvas bags and stuff on the ladder for recovery gear, wet stuff, rubbish etc, to free up some space inside, so you may be looking at 10 - 20Kgs tops.

Starting to think about building my own ladder. How hard could it be!
