I had the hitch adjusted when the trailer was fully loaded. Had to stop on one of our trips to get it adjusted. They leveled the hitch so that the trailer matched the trucks stance.
The carrying rack I used 3 of the receiver mounts spaced out across the bumper. The two outside ones are close to the frame mounts and the middle one is in the middle of the bumper. By doing this, it prevents the rack from shifting due to weight. The front edge of the rack is about 1 inch from the rear bumper.
I do like the looks of the front mount carrier. I can also carry my generator in the back of my truck but that is a hassle to move when I need the bed. Being disabled, 150 lbs is hard for me to move.
Thank you all for your input and ideas. It has been very helpful. I will update when RNR in Spokane figures out what is causing the problem. They have been great to deal with so far.
