how can I find out if my heartland sundance travel trailer is part of the 99-01-12 axle mount recall. I have had sway problems since we bought the trailer. I have towed landscape trailers for about 20 years and just assumed that since an rv is taller and has a higher center of gravity it was normal. Our family camps fairly light we do not have the camper jam packed and we travel with our tanks empty. I have a 2013 310bhck and we purchased it at the Hershey rv show in oct 2012. I read that it only effected the 322res but if the only difference is a foot wouldn't they use the same frame and axle placement? I know the 322res has a different floor plan. I am concerned because my rv was supposedly 1 of the first 5 made. Is there any measurements from center of axle to rear of frame or where the axle placement is supposed to be so I can take measurements. Any information would be greatly appreciated
