Greetings all! Just new to the fun game of pop-up trailer camping and towing. Wife and I tossed our old tent after labour day and got a new to us trailer. Vehicle: 2021 Grand Cherokee L equipped with type iv towing package and engine upgrades. PUP: 2008 Fleetwood Utah. So i hook everything up. Trailer is attached to 2” ball, cross the chains and attach the emergency brake wire, plug in the trailer to the truck. No problems! Start towing down my street and feel the weight of the trailer being pulled. No big deal for me. I turn on to the next arterial road (60km/h max) and I’m driving 50ish and i start to get this sensation that the truck and trailer are having a tug of war match. Like the truck feels like the trailer is pulling back and forth (now swaying was occurring). FIgure maybe it was some pot holes and drive onto a smoother road. As I’m driving i find I’m getting the feeling pretty well the whole trip. It was the most stressful 80km drive ive ever had. I still cant figure out what happened and am not looking forward to driving home on Monday. Anyone ever have this experience before? Please help!
