Remember when I told you that I broke my steps into the motor-home? There was a long shoulder bolt that broke off at the shoulder. The treaded part was three eighths diameter thread and the upper part was half inch diameter by three inches long. It holds the gear that lifts and lowers the steps. The bottom cover plate that the head of this shoulder bolt rests on, was bent also. I fought that thing for a couple of days and finally was going to give up and try to get the whole unit out and take it to the RV repair place. If I couldn’t get it out, then the RV would have to go to the shop.
