I use a caravan step at home (and a beer crate when traveling - new one every time!)
I started by throwing it underneath the camper, but it ended up full of sand. And at home, I'm in the middle of a build at the house (carport, driveway paving and small workshop) so no decent storage yet.
So I came up with this piece of engineering brilliance... £2 pair of S-shaped cookshop hooks that hang on the roof ladder, then the steps hang on the hooks. Bungees for a bit of extra security.
This isn't a road transport solution BTW, there is a proper mounting bracket on the EC6 when on the road!


Keeps it out of the way, and I won't drive over it!
