Whitecloud, have you considered what brand you are interested in. I have had wonderful experience with PJ. If you are interested in hearing more about my expiriences just private message me. I have 2 PJ's, a Hudson, an Appalachian, and a couple different car trailers and enclosed trailers. You can never have enough but i have one that is set up for pretty much anything. With a 3500 Cummins, if you are willing to spend the coin i would recommend a gooseneck for your application. I will warn you that the low profile goosenecks can be a pain depending on what you plan to do with them. I have found that the low pro's tend to get caught or rub in fields and steep driveways. I am fortunate enough that most of my trucks stay hooked to one particular trailer most of the time. I will tell you that I strongly recommend the B&W gooseneck ball if you decide to go with a gooseneck trailer. I have them in 2 of my pickups and love them. Like i said feel free to contact me with questions.
