I generally don't even hook up my sewer line until I've been there a few days. Water and elec I hook up right away if available, but the tanks are good for a couple three days even when we aren't being conservative. After a hard day towing, one must minimize setup and maximize relaxation. This means strain yourself a little setting up the zero gravity chairs and opening a beer or two or.... Sewer can wait. By the way, I'm only familiar with the term "Poop pyramid" through campfire horror stories, and later in life the internet forums so I can only vouch for the method I use as working.
