Need to fix my step on my Arista

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.
