Good point. Santa Rosa does require one to back out. It isn't pull through so its a spatial challenge when pulling a trailer.
Ogallala, NE is great for that. It has a row of back-in Superchargers but paved roadway going behind them all. Not trailer pullers can back in normally, but trailer pullers can drive through behind and use any pedestal that is free!
I've noticed some new SC wont work like this. In some installs I've started to see them install plexi in the SC hole so the cable would have to ho out and around the SC and thus not have enough length to reach the back where you're officially not supposed to be plugged in.
