I thought that the "steps disable" switch had gone away sometime around 2010 (Consumer protection folks) so that the steps would always extend if the door was opened and always retract when close. Our rig has the disable feature. We were on a State ferry early this year (as foot passengers) a big DP came on board and, as is typical, got parked very close to the vehicles in the next row. The one alongside was a new Mercedes 500 sedan.
One of the MH occupants opened the house door and there was an almighty "clang" as the steps extended into the side of the Mercedes. I'm sure glad my GT still has the disable switch. If you know the steps aren't out you can improvise. Better than a $5000 claim against your insurance.
