Gas stations can be a "challenge" so to speak.. But If you are selective it can be pretty easy with the right station layout.
The layout with the check mark is my preferred layout..
Traffic flow is parallel to the store.
The layout with the red X can be a real pain.
Traffic must flow towards the store and often the store has parking in front of it.. Makes for a lot of traffic with very little room to swing a trailer.
We tow a 26 ft TT with a pickup truck, and so far as of yet never used a "truck stop" station like Flying Js.. To me truck stops tend to have a lot of busy big rigs moving about.. Those drivers make money only when their wheels are turning.. If I slow them down they make less money..
