Pilot Flying J, I use the app on the cell phone to find a RV lane and then use there discount card to fill up only swiping the card 1 time. In the 3 years of full timing we have had to unhook the toad 1 time and had several very close quarters pulling out, but sense getting the Pilot card and app no problems. When we pull over for the night I look up where my next gas stop will be and put the address in the GPS. We only travel about 300 miles or less a day so it's not a worry for me to get gas. I only use about 1/2 tank of fuel between fill ups.
