Your manual may state it but you may have the model water heater that does not have an Anode rod. The Anode rod and the drain plug are one and the same.
Just to be on the safe side find the make and model (usually listed on the placard) and do a quick web search online to see if it originally had one (if your TT is used). Or contact Jayco with your VIN and see what model they put in.
