Thanks for the input guys, my king pin will be at the rear most point on the deck behind the toter home box. The trailer i am pulling weighs somewhere in the range of 17,000 and is pretty heavy on the king pin. The twin screw axle locations are not set in stone at this point. I know this is not good logic from an engineering standpoint, but out here in rural kansas guys convert regular over the road tractors to grain hauling trucks with 20' boxes on the rear, hauling 600 bushels of corn * 60 lbs/bu = 36,000lbs + the weight of the bed, with virtually nothing hanging over the rear axles. To my knowledge the front axles are not being upgraded in these trucks??
