I see no responses to your question yet so lets get you back to the top of the list again. It always helps if you provide the year of the coach and maybe who makes the stabilizer system (model number etc) if you can. Sometimes Thor installers don't always put things like breakers in the same place either. I can't answer your question, but if this is a Lippert electric stabilizer system the "typical" schematic info (link attached) says its a 20 amp fuse or breaker minimum. I would also expect this to be installed close to the battery location, or the jack motor location, but that is just a WAG. They also show a 6 amp reset breaker.....so if you have also have that in your system it may have also tripped. Hopefully someone with your coach will respond with better info.
