I dont know that it would make a difference I was just curious. I know when I was in the trucking industry, there were some companies that would raise their 5th wheel 2-3″ higher off the frame of the truck, to transfer more of the weight (granted most were tankers hauling liquid of some sort) to the back of the trailer, so they could haul more product. Otherwise there was too much weight on the truck axles to scale a legal load. Was just a thought.13 PIV w/ 200 MercIG: WarriorRiverCustomRods
