Thanks, I called the dealer today, he started to say that when you put a load in the back of the trailer it would reduce the weight on the tongue. then he went on to say that the round bars are the ones rated for the 800 lbs and if I wanted the 1000 lbs bars he would swap them out but the actual portion that the ball is on would stay the same. I have an RV-pro, model #22-8201, it has a gross trailer weight of 10 000 lbs. I'm really new to all this stuff, I have pulled lots of trailers but nothing that ever required a weight distribution hitch.
Is this dealer correct with his answer that it's just the bars that are rated for the 800 lbs?
