In addition to the good advice of planning your exit, looking for pumps that don't force you into the parking spots in front of the store, and looking for stations on the corner;
Grow a thick skin. I have gotten myself swung around, heading for the front pump at a station, only to have a jerk back into the pump I was aiming for. So there I was, blocking the normal traffic pattern with my trailer, with no good way out until the jerk decided to move. (I'm usually rolling solo - no spotter) Those situations happen, and you just have to deal with them.
Like some others, I will put in 600 mile days and stop for the night without unhooking on my way to my destination. I want to spend my vacation time in Death Valley and Joshua Tree. I don't want to fritter that vacation time away on the way to the destination.
