I am guessing that there is two holding tanks (bath1 bath2 switch ) on my r wagon ? However i cannot find anything to be certain . Anybody know how to opperate this properly ?

You are probably looking at one grey tank and one black tank. Do these switches show a level by chance? If they do you may want to figure out which switch for which tank, BUT if that's what they are after the first use the level sensors generally aren't accurate. Just dump either tank when they fill. If these are electric dump valves, then you would need to figure out which is which. Again, just dump when full or near full.
