To choose a weight distribution system, you'll need to first determine the fully loaded and ready to tow tongue weight of your trailer. To that figure, add the weight of any gear stowed in the cargo area of your Durango behind its rear axle. I've linked to an FAQ article that explains how to do this. These combined figures make up the Total Tongue Weight (TTW) of your set-up. The TTW of your trailer should fall as close as possible to the middle of the effective range of the weight distribution system you choose.

For the purposes of making a recommendation, I'll make a guesstimate of your TTW. However, it's extremely important you determine this for yourself. Your Tongue weight is most likely between 500 and 800 lbs. Your trailer is fairly long, and therefore more susceptible to sway caused by cross-winds or oncoming traffic. I'd highly recommend you go with a system that combines weight distribution and sway control. The Reese Steadi-Flex system, part # RP66558 is effective on trailers with tongue weights ranging from 400-600 lbs, and should work perfectly for your trailer. In the unlikely event that your TTW is greater than 600 lbs, go with the # RP66560, which is rated for a TTW of 600-1200 lbs.

Both systems I recommended include a weight distributing shank, but the trailer ball with the 1-1/4 inch diameter shank is sold separately. For a 2 inch ball, use part # A-90 or # 19286 for a 2-5/16 inch ball.

I've linked you to an article that explains how weight distribution works, I hope you'll find it helpful.
