What model is your motorhome? Not just make? What is the hitch allowance? What is the tow allowance? What does the coach weigh loaded? What is it's unloaded weight? What is the GVWR? What is the GCWR? What are your GAWR? Where does you coach fall within these? Do you have the owners manual. Do you know the weight specifics? Axle weight specifications? Have you weighed your coach? What does your trailer weigh loaded? Are your tires aired to the loaded weight? If your airing them properly your tires would have different pressure traveling with the trailer vs without. Especially without a weight distribution hitch.
Until you now these things it's just a c rap shoot.
