[s/b Master Tow] Roadmaster dolly skid plate jumped... :(

Could help, to clarify the Make, Model, even Year if you have it. Some of your text says TOWmaster, text and title say ROADmaster, and the picture shows Master Tow. I'm not an expert, but I don't think Master Tow is a Roadmaster product. Clearer you can be, the more likely somebody's going to match up a similar product or experience.
