I'm thinking they're both the same size Dave....(on the pumps AND the coach).
I've had a time or two where I've had to wiggle with the nozzle to get it down the neck and I use a LOT of Flying J's.
Seems like those are the times I need to slow down and take a breath....read on!!
This last trip it was chilly and I was in a hurry and NOT thinking and stood in front of the pump when fueling.
Well, the pump kicked back and soaked the t-shirt,jeans and shoes I had on...so bad that I hustled in the coach and changed, then THREW AWAY the clothes.
Gotta be thinking all the time when you're around those high speed pumps...
