Thanks all,
So now my concern has shifted to my long dirt road entrance to my MILs farm in GA. There I have more extreme versions of this angle and the opposite angle. As you all have indicated it is the valley, not the hill to worry about.
I would not want this device to try and raise the dually rear end at the expense of the aluminum trailer frame when I encountered a valley. Perhaps when I got to this part of the journey, I would get out and release all tension on the bars as it is low speed travel anyway.
I think I will pull without a WD first to see if I need to replace weight to the front axle or not. Maybe I would just need a sway control device, not a WD device? For example, if you had a semi truck tractor and put an 8k travel trailer on it, the tow vehicle is going to be just fine, the front end is not going to come up. Does the WD hitch still play a role here by helping the trailer physics somehow?
