John,
We were all dummies once!
Just ask away. On our first outing many years ago, we had no idea how to dump. We didn't even have the right equipment. Thank goodness there was a nice old gentlemen parked across from us who told us what to buy and when we came back from Camping World he came over and showed us how to hook it all up and how to dump. Thank the Lord for him.
Happy trails.......................
