I think I know the answer, but wanted to check with the experts to be sure. I never used a WDH with my 2500 Ram, never needed it. Now that I’ll be towing with a 2018 F150, I’ll need it, so it arrived yesterday. I have the trailer marked where the front tires of the Jeep would go when I towed with the 2500. When I setup the WDH for the first time, do I set it up with the trailer unloaded, then load the Jeep and mark the new location where it needs to ride for everything to be level, or do I load the Jeep on the trailer first, then setup the WDH? The head of the WDH has several angle settings to adjust. If I load the Jeep first then setup the WDH, if I’m pulling the trailer empty, would I leave the trunnion bars disconnected?
