How hard to replace siding on 2 year old trailer?

My 2015 North Trail is also delaminating and I will attach what the company gave me as to "How to fix". Guess the page will not allow me to insert a PDF file.
As you will see, its complicated. First thing I had wrong with it. May not ever buy another from them. I keep it garaged in winter, not good. I will try to send it directly. I like the hurricane idea....
