I drove my 04 Dodge diesel to Myrtle Beach and back this past weekend. I carried three 5-gallon cans to fill up on the way back if things looked sketchy. It's 314 miles from the house to the camper, and my truck will do it on a half tank if I don't run 80 mph. I filled it up when I got to the beach, and stopped in Spartanburg on the way home and topped it off. No signs of a shortage, but it may not have materialized yet. My extra cans are still empty except the one I keep full for my tractor. Who knows what will happen!?!?
