I bought a maceator and some brown hoses so I could set my TT up in the backyard and use the facilities. Haven’t used it yet.
But about 10 years ago when my township hooked up to city water and sewage, we had to clean out and fill our septic tank with gravel. Then pipe in a bypass to the new sewer line. Part of the city system required a clean out access. I cut some low branches off the tree in the narrow side yard and can pull my TT right up to the clean out in the front yard. Run a water hose (2) from the other side of the house. Only one way to get near the clean out due to various levels in the yard and my drive cuts down to get to the road.
I try to schedule last camp of the year at a full hook up site, so no military precision required ;)
