Below is the “almost” comprehensive list that can be used as a guide to help any RVer to keep track of the many model numbers and various parts on an RV that require such information. Almost all RV appliances will have model numbers that are required in order to look up replacement parts for them. Quite often there are many parts that can have many versions of it that look similar but aren’t interchangeable. Screen door latches can be a good example of that. There are at least six styles that look alike but aren’t interchangeable. I recommend that you take pictures of the tags that have the model number on it and picture of almost everything else and keep them on your phone organized in a file system. Each RVer will need to determine if pictures, a book or spreadsheet will work best for them. I highly recommend picture in an organized system, The RV Parts Guy at the store will love you for it.
In some applications a model number might not be that accessible and a picture or two will probably suffice.
