I'm watching a documentary on H2 about a truck convoy that delivered supplies to an oil field in Alaska. In it the stated the trucks had to be left idling overnight to prevent freeze up which is understandable, they probably wouldn't ave been able to restart them. They also claimed each truck burned 80 gallons of fuel idling overnight, I find this hard to believe. These were standard road haul trucks, not oversized behemoths with mega engines and took place in 1969, at time when diesel power was at modest levels. From my experience in driving and refueling those trucks, I'm having a tough time swallowing this. Anyone know different?
