Finding an older model owners manual is usually not worth the effort. The manuals are written very generically to cover multiple models and changes made on the production line. Since the number of models produced is low and not worth changing the manual to be accurate. Take a survey of your RV and note every item installed. Those systems most likely have manuals, even troubleshooting guides to help. You can even read owners manuals for current RVs available on their manufacturers websites if you'd like.

under the hood there will be a fuse block usually behind or near the battery. pull the cover off and on underside of cover there will be a diagram you'll need your manual to find the right fuse to replace

Thor never made that model so they will not have that information available. Thor bought Damon around 2011-12 time frame. Many places that fix RV's will tell you that if you bought a Damon product before Thor bought them, it is probably still in good condition and has needed minimal fixing but anything after Thor, forget it. At least when you throw your money in the toilet you know why you lost it.

Try eBay

Contact the manufacturer of the coach for their owner's manual. However, each appliance will have a separate owner's manual form its perspective manufacturer, i.e., Water Heater = Suburban, A/C = Dometic, Refrigerator = Norcold, etc.. There will not be a diagram of electrical or plumbing as a majority of the RV manufacturers do not publish that information.
