We try to fuel at a Flying J/Pilot where we use a loyalty card to get a discount. Every one we have fueled at in the western USA had a RV lane with a smaller nozzle in the truck pump area. The flow rate is at the truck level and the tank is filled 4-5x as fast.
With the non-truck stop places we have to go inside to not have the pump shut off at $100 so no different from a truck stop most of the time. At the gas stations we often have to wait for a pump to open up that we can get to and fillup and not have to bakup to get out of the space. Motorists as a whole are so completely tuned out that they will often pull up in front and in back and wait for use to finish and when we do there is no place for us to go. No such problems in the truck lanes.
