So recently purchased a 2021 380FL. Although it has the 17.5" wheels and H rated tires it does not have the 8k axles. I am certainly concerned about being overloaded after looking at the CCC on the sticker. I am thinking about upgrading to 8k axles this winter while I am at my home base in FL. However, I would like to know roughly how much more CCC I would be getting. Can someone with the 8k axle upgrade tell me what their CCC is? I know it would not be exactly the same, but it would at least give me an idea. I will say that the 7k axles I do have are 3.5" and Dexter has 3" 7k axles and 3.5" 7k axles. SO there is that. LOL. I just don't want to spend the money if I am not going to get a clear increase in CCC. I am certain the answer isn't a straight forward 2000 #s . Thanks
