Some places make it .. Hard.. For example today I pulled into a Shell and used my Rewards card to get a discount (Only a few cents but a few cents times 50 gallons......) took three cycles of the pump to do it.
I basically choose a station by physical attributes.. At this shell I was able to pull off the road in the manner of pulling off onto the shoulder, "Slide" up to the pump, gas up and pull back on the road in much the same way. Did not actually "TURN" into the station.. This is the absolute BEST layout of a gas station EVER for a motor home... That fills on the curb side.
Other stations I've had to drive very very very carefully
But not that one (Circle K.. Georgia HWY 17, South bound, Darien GA)
