Got to be careful at some places where they have easy pull-in and then you are trapped to get out... A couple of RV FRIENDLY truck stops like PILOT FLYING J have RV pull thru spots.
RV FRIENDLY FUEL STOPS
We always carry a couple of 5-gallon fuel cans where if push comes to shove you can always park in a good area and walk-in for fuel. You can also park somewhere and unhook from the trailer and take you truck anywhere then to get re-fueled...
We sort of got into only driving until around 4PM each day and then finding a stop over campground spot. After setting up then will go get the truck fueled up for the next day trip...
