I can (just) see that my predicament has provided the required amusement for all. A comment or two:
Although I prefer to think think I am not a complete dufus, I am unsure that a checklist would have made any difference. I walked completely around the vehicle, checking for loose hatches and doors, tie downs on the cargo carrier in the rear hitch, etc. What I failed to LISTEN FOR was the motor retracting the steps when I closed the door. Period. The only other thing I could have done was to adjust the shotgun side mirror to actually see if the steps were retracted once I got into the driver's seat, since the switch leaving the steps down was activated--ie., the steps were down, regardless of whether or not the door was closed. There is no warniing light if the switch is activated.
I was hot and tired. Fatigue will cause most failures.
I have managed, through too much effort, monkey wrenches, come-alongs, and big cheaters, etc. to get the steps to retract manually, although I don't think they will ever be pretty again without application of fire, anvil, and hammer. A family conference has determined that new steps should be purchased for safety and reliability. Suggestions as to a source, and reasonable price??
Best to all,
