I bought Dorman 090-175CD Oil Drain Plug as part of my camper van equipment.
The drain plug is part of my vehicle-service purchases, separate from the fabrication and interior materials in the hub.
Where it fits my build
While fitting the heater below the passenger seat, I worked underneath the van on the intake, exhaust, fuel filter and pump mounts. The black substance visible on the undercarriage was Fluid Film Black, which I had applied across the underbody while leaving the exhaust parts uncoated.
Much of that session was spent lying on my back. I recorded how cramped the space was and how tiring it became to hold my head up and work with both hands around the mounting points.

My build notes
The diary separates the coating already present beneath the van from the heater work happening that day. The photos are useful for seeing the available working space and the location of the lines and attachments.
The available space under the van affected the pace of each mounting task.
