Yep soil pipes are nice but in a small van where the pole has to go diagonal to fit they aren’t a lot of use. Because you have to slid the pole a long way, diagonally they would hit the rear doors. Unless you opened them 180 degrees every time. Pain in the bum. My way is split seconds hand on the pole. Soon as you undo the clipped end you can move it sideways before lifting it of the bulkhead end. Simple fast efficient.
