Amazing really, like Jayco you shouldn't be able to supply something that can potentially break somebodies leg! There's an Australian standard for steps in buildings and the bloody RV industry should look at enforcing it.
That's it. some manufactures are now building vans without the internal step depending on layout for exactly that reason, usually models with front bed and door, people getting out of bed and falling on the internal step breaking ankles etc. in turn though they have to add at least 2 external steps.
