I used to haul a 34' deckover...its a piece of cake as long as you don't have to get into a car diesel pump!
No s***! I had to fuel up a Kenworth pulling a 53' dry van at a Stuckey's just outside of Ihearbanjomusic, TN. It was like putting toothpaste back in the tube.
I had much better odds of scoring some bathtub speed than fitting into the fueling isle.
