This weekend our fuel tank got punctured on our 3500, and leaked out about 1/2 tank of diesel before it got plugged. Had to replace the tank. Dealer said something must have bounced up and put a hole in it. Has anyone heard of this? Does anyone know if there is a skid plate option available to help protect the tank, since they are all just plastic now? The truck was parked at a horse show, so it would have been pretty obviousl if someone was trying to steal diesel, and besides, it was just pouring on the ground, so it was not like someone was after it.
