I have driven class a but this will be my first time pulling an RV trailer. I have a ram 1500 and I’m looking at getting a grand design momentum 21g. Looking for recommendations on what is a good set up. Is there an all-in-one unit or do I need two separate units and what do you recommend? I figured I’d see what people are using and then start my research from there on where to get it and how to set it up properly. Thank you for your help.
