Thanks again guys for your notes. I think I will invest the little cost to get this setup. On another note I decided to talk to one of the folks at the dealership who they referred to as the (expert). He mentioned that once again it wasn't required and actually said it could be harmful for this setup. He said that since this rig had a lower than normal TW that the WDH could actually cause the TW to be lower than the 10% requirement, and could cause the rear wheels to be too light on the road. I guess that might be true on a totally empty load so I'll just make sure to balance everything right.
