Our 2013 diesel pusher HR Ambassador (38 foot) with Roadmaster chassis wanders and constantly needs steering wheel correction. Also the mirrors vibrate and the shades along side of the driver really vibrate when driving. When stopped and you turn the steering wheel back and forth you can feel and hear a slight clunking noise. We previously owned a Simba Safari Motorhome and had none of these problems. This has occurred since it was purchased brand new. It now has about 17,000 miles on it
