I can relate to your pain and suffering. I too took on a dmax last summer when I had my 07 6.0. I honestly bet him in two straight up heats but then we decided to hook up a chain and have a pull off. I twisted my front driveshaft so bad it pulled it out of the spline. Then I had to quit and lost the pull. But guess what....I have the coolest trophy in the world for being the loser!!!!!!
Merry Christmas
