Finally got my diesel

Well, I agree that the electronic sway control is reactive. It will take over when the sway bar is over taxed. It only takes a second to install it. The owner's manual says that the wd is optional but I like the idea of using it to help control porpoising. (Wow, how do you spell it.) I currently "hang three" so I will hang two. The truck hitch is a class five and my utility head is well in range for my trailer, so no concerns there. I did go to the other thread for more info. If I had my fifth wheel, this whole discussion would be moot. Thanks and a special thanks to those with the same set up.
