I've had numerous step issues and as a result have learned how to do repairs myself. Also learned quickly that you do not want to be in the action area when they deploy or fold in. I have the Lippert double electric step assembly. Broken shoulder bolt and broken link end recently. I think I am on the Lippert list as a frequent buyer now. But, I am glad to say I have not had a bowed frame. Sorry I can not help.
