I created a small spreadsheet for all the appliances in my unit. It contains all pertinent info. Some was provided on a scribbled sheet by the dealer, but much was collected from the actual appliance data tag. This a project that can easily be accomplished on a lazy afternoon at the campground. I have make, model #, serial #, mfg date ( if available) and any other important data. I have a copy on phone and in TT. This way if I need a part or have to check a SB or recall, I don't have to uncover and scramble in the heat or cold.
