2021 White River Marine Group Boat Trailer

I have control issues due to inadequte suspension. The problem I'm (and others) having is due to the suspension on these trailers. When pulling the trailer on the roads there is exessive bouncing to the point where one could lose control. Personally I have checked my trailer wieght, vehicle weight, tounge weight, etc. and found everything to be set up correctly but I cant solve the bouncing. I also had it in to the dealer and asked them to check the trailer, they said they pulled it with their truck and felt it was normal. The issue is somewhat road related and is worse on different roads or even on different sections of the same road but there is no warning. Some roads are so bad that you cant have a conversation because of the repeated bouncing. The trailer is made for road use so it should be safe on all public roads. The worse roads are the concrete freeways and I find some roads are almost unuseable to me. I thought maybe it was just my setup but then I joined a facebook group called Nitro ZV Nation and found that many others in the group have the same issues with bouncing and also excessive suspension noise. A lot of people have posted that upgrading their trailers suspension (shackles, equilizers, some case leaf springs) has resolved the issues caused by these parts. Some of these trailers are only a year old and this shouldn't be required by the owners to make them safe. People have posted pictures of how worn out and egg shaped the mounting holes for these parts have become, very dangerous looking. And there are people who are unaware of what is going on and coping with the bouncing. Left unattended this will eventually worsen and become even more dangerous. I believe these problems are caused by poor design and/or inferrior parts. The inadequate suspension leads to the trailer bounce which leads to parts wear which leads to more bouncing, etc. I wanted to make the safety administration aware of something I feel should be looked into further.
