2020 NEWMAR LONDON AIRE Complaints

UNKNOWN I was traveling in this new to me 2020 Newmar London Aire on a trip of approx. 2,700 miles. The first issue was coming to a bridge in SC that was maybe 400 feet in length. There were lots of transition strips and dips on the bridge. When I first approached the bridge, my Motorhome bounced/propoised so violently that my wife flew up out of her sit and the front end dropped to the stops on the frame. I have been MHoming since 1999 and have never experienced this type of bouncing. I was scared and the MH continued to bounce on this bridge for another 6-8 times, although not as violent as the first bounce. We experienced this bouncing/porpoising many other times on our trip, just not quite as violent as described above. This is a major safety issue and it has to do with improper shocks/ no sway bar on the front axle. The chassis is Spartan and I talked to them about the problem but they played dumb, even though I have communicated with many other MH owners who have experienced this same problem with this K3 Spartan Chassis. Those owners have also talked to Spartan and have not gotten any satisfaction.
