As long as you don't wait until the last few miles of range to get fuel, there should be no problem. Many stop for fuel somewhere around 1/2 to 1/4 remaining fuel. That way they have the choice of several stations without being stuck with the last station available before running out of fuel.
I've filled up at some small stations that had plenty of room for a big rig if you happened to go to them when the pumps were empty.
Basically, if you are below 1/2 tank, and you see a station with easy access, stop and top off the tank.
