GMC G7106 1,5 ton 4x4 Cargotruck / dumptruck (as seen on every 8th AF airfield during WW2

These trucks were also essentiol when the allies invaded Europe, not only in the rapid airfield construction following the advance but also in carrying fuel:

Distribution of gasoline from the ports and from the pipeline termini remained major problems throughout the war. Tank cars had to be brought from England and from the United States to increase the carrying capacity of the railroads. The IX AFSC had to organize additional bulk truck units and called regularly on the Communications Zone for supplementary carrying capacity. During the closing months of the war, when the swift advance of the Allied armies once more stretched taut the supply lines which had been carefully strung during the preceding months, truck and air transport had to bear the burden of carrying gasoline to the forward airfields. By April 1945 the POL distribution system could transport 150,000 barrels (6,300,000 U.S. gallons) of gasoline per day.126 Considering the tremendous forward lunges made by the Allied armies and air forces during the summer of 1944 and again in the spring of 1945, the trucking units of the IX AFSC and the Communications Zone, and the latter's military pipeline service, did remarkably well.
