Well, you did make a mistake if you didn't get the HDPP. If your payload sticker isn't close to 2000 lbs you will be on the edge of safety, and your comfort will suffer when towing.
I have a similar trailer with almost identical weights. Your hitch weight ain't gonna be 830 lbs. It'll be closer to 1000. My HDPP handles an 1100lb tongue and 8500 lb trailer great with 4 in the cab. The EB I had before was just Max Tow and it didn't have enough payload and I was overloaded most of the time and I could tell. Now I know better.
