FDrake said:EMD diesel power, Be sure to remove the tube sand in the winter if you are in an area that gets freezing weather. The tube sand will get wet and then freeze solid. You have no idea what that tube sand becomes if you have an accident or something causes that tube to leave the bed of the truck suddenly. One thousand pounds of frozen sand acting as a missile is NOT a good thing to happen. It will go right thru the rear end of the truck if it gets airborne.
