We use pilot / flying J almost exclusively, I got their RV frequent fueler card, and it does turn on the truck pump, and also discounts the fuel, I think by a nickel. I use the slave pump too, and can zap in $300 worth of diesel in just a few heartbeats. Use an open pump with no one parked in front of it if you can, the truckers will fill up, pull up, and then go in for a sit down meal and a shower.... :)
No way do I use the RV lanes unless I need propane and there is just no where else to go. Typically the RV lanes dump out right at the building with no way to turn a big rig, and they are full of jamokes in lil delivery trucks to boot! It used to be ok, but now that they charge to dump regardless, fugetaboutit.
