Since some don't believe that the layout I don't like can be an issue, I wanted to post a pix of a local station that I don't dare pull a long trailer in, heck even a pickup truck can be a challenge to get out when this station is busy so I avoid it at all costs..

That station I added in green the orientation of the islands under the cover, islands are the full length of the cover, there is less than one car length between the end of the islands and the car parking spaces in front of the building..
You simply cannot make a turn with trailer in tow between the station building when the parking spaces are all filled.
