First thing: When you go to fiddle with it....Unhook EVERY battery on your RV. An unexpected movement of the step mechanism under power can easily chop off a finger. RVs vary, some power the steps off the house battery, some off the chassis, some have a transfer arrangement so it can be powered by either. Be safe! You will find the motor is out of sight above the top step. You will have to unbolt the rod that connects the steps to the motor for them to move away and expose it. With any luck, you'll be able to straighten whatever is bent after you get it all apart. A big hammer and a concrete road is your friend.

There's an on-off switch which I shut off after I disconnected the batteries so it's disconnected and the switch is off, no chance of the motor turning. I could see where the steps come apart so I'll take it apart and then look in there and see if I can find the motor see if there's a rod that's bent.

I wasn't sure if it was a rod that pushed back and forth or a screw mechanism.
