Since you all have been awesome at helping me out, time to ask another question. Should I be greasing my weight distribution hitch arms and ball? If so, with what?
I also use tube of lithium grease. The small opening on the end lets you put the grease where it is needed. When we do our final set up after about 6000 miles of towing I use plenty of paper towels and some WD40 to clean up before our next run.
