A few years ago, I received a request to build a fuel truck for a fellow POL troop. That request started a long journey that continues today. In the gallery below, you will see many images of how my design has evolved over time. I currently make the Oshkosh R-11 model in three sizes, 12″, 17″ and 24″. Each model is very close to scale from the tank dimensions to the holes in the front of the grill.
