Being trapped in the big rig fueling lanes is what caused me to install a auxiliary fuel tank so that I never need to stop while towing the fifth wheel. After we arrive at our destination, I'll unhook and go and get fuel out in front with the rest of the passenger vehicles. And that's where the pay at the pump works too.
Sitting out in the back in a line with the "real" truckers waiting on them to finish shopping, eating, watching a movie in the lounge or taking a shower was more than enough motivation to install the aux. tank. It no longer takes 45 minutes to get fuel.
