Yes, the purpose of the pipe through the wall is to pass through the stinky slinky hose and dump from where I park the camper.
I wasn’t going to dig any closer to the garage footings because I know what’s under the ground there: Two corrugated drain pipes and our electric service. I wouldn’t have been able to get much closer anyways, so I kept it close to the tank lids that I already have to avoid driving over.
Since I couldn’t have it inside the garage, a few more feet didn’t matter to me.
