Congrats on making it to your destination safely and for providing the excellent report.
Diesel pumps for truckers are a little different. I was driving a Diesel UHaul pulling a trailer once, and I didn't want to deal with the relatively small, crowded car fueling area, so I went back with the truckers. After years and years of putting a fill nossle right into the tank, its a little odd dealing with ones that sort of clip to the outside.
