That is, I got no crap on me, Ava or the ground during my first solo dump of the tanks. Movies like RV with Robin Williams can freak a guy out about all the bad things that can happen when emptying your tanks.
So, as an engineer I made sure I understood the system as a whole. I read a lot of instructions on proper technique and how to avoid contamination of everything but the sewer hose. And I watched an inordinate number of Youtube videos on RV black tank mishaps and how to avoid them. My biggest concern was that there would be pressure from a line of people waiting to use the dump station. But when you are at a state park in the New Mexican desert, in January, on a Tuesday you pretty much have the dump station to yourself.
