233S Fresh Water Tank cap
I'm a new owner of a 2012 Roo 233S. During my walk through, the sales staff told me that the fresh water tank cap was in the outside compartment of the water heater. I even remember seeing it in there when we did our walk through. However, since we have gotten the camper home, the fresh water tank cap was not in there, nor is it installed on the camper.
It looks like just a simple threaded end cap that I could buy from any hardware store, however, I do not know the size that I need. I searched through the owners manual looking for anything that relates to the size and thread count of this cap and I can not find anything.
Any help you can give me would be greatly appreciated!
