Sorry for bringing this thread back to life...
We just completed a trip from Ohio to Florida and back without our trailer. Along the way in the back of my head I tried to see how many RV friendly fuel stations were along the way that sold diesel. I didn't see too many that would allow a 1/2 tank allowance for my 26 gallon tank and most if not all had their pumps aligned perpendicular to the store.
Has anyone been in such a pinch that you have dropped your trailer in a parking lot just to fuel up?
