We purchased an Amped 28FS in October. We have taken it to the Dunes which is 4 hours away like 4 times and on two other trips without our Polaris razor 1000XP. We have put the razor in forward and backwards, went with tanks full and empty and I am white knuckled driving the entire 4 hour trip due to swaying. We have a 2015 F350 diesel. We upgraded to 14K Equalizer sway bars at our last trip into the dealership and they barely made any difference. We LOVE the actual trailer and how it accommodates our family and our needs but really need to figure out why the trailer is pushing our truck all over the road as it's dangerous for our family. I do drive trailers all the time so have experience driving with trailers and have never had this problem before.
