I have a L-Shaped WVO Tank used in a truck bed. the tank is designed to fit under a crossbox. The tank is the best quality you can find. It was made by one of the best tank welders in the country, Greasekings. The tank has a fill, drain, oil in/out and a fuel sender. It also has a heated pickup built in. Has bolt holes to bolt to truck bed. Paid ~$900 new b/c the quality of the welds and thickness of aluminum used along with the overall design.
