I'm not into the specs and cyphering numbers but if you hook onto a 30' 10,000# trailer you're gonna learn the meaning of, "The tail wagging the dog." WD hitches aren't the whole remedy, they only help marginal applications. I bought a cabin cruiser that weighed 8000+# and I thought I could tow it to the local lakes. The 1/2 tons, Jeep & Ford, did a pretty good job until it got a bit windy. The trucks went where the boat wanted to go. Not fun. The 170" wheel base of the F-350 doesn't even begin to waver. Your short wheelbase Dodge is a deterrent to a stable tow. Our toy hauler is rated at 11,000# and I don't bother to hook up the WD bars on short camping trips. As I think you will learn, or are learning, getting your first or even second unit is a learning experience. One bit of advice, don't believe what the trailer salesman tells you. They tell you what you want to hear to sell the trailer. After the papers were signed and the 11,000# purchase was a done deal the salesman ask what I intended to pull it with?...... I think you did well by signing on here. There are many RVers here with many years of experience that went through the same growing pains that you have now. Prepare to adjust... The best of luck to you.. :)
