My wife also falls out of our camper. Lucky for her, I've been there both times to catch her. I now insist she goes down the steps the same way she went up; face into the camper. I told her to not think of these as steps but as a ladder. You wouldn't come down a ladder facing outward, you would face the ladder. So with the camper steps; think ladder. Since then, she's done much better and I don't worry that I'll come back from fishing to find the turkey vultures gnawing on her carcass.
I'm pretty sure the local DA would say I pushed her...
