I got a factory hitch for my 2017 3.6 OB from the dealer when I b I'm looking at something like the attached picture. I was just at the rv dealer and we put the the trailer hitch on a scale and it came in at 350 lbs. The factory hitch max tongue is 200 lbs? This is empty. I'll likely add 50 to 80 lbs of battery which goes in the front. So is this out of the question?
