I think you would have a hard time getting this to be a warranty issue. Maybe a goodwill gesture from your dealer but probably not Nitro. I have owned way too many boats thru the years and I could load most of them with the trailer pretty much at any reasonable depth. My personal opinion is this is something that should be covered by the dealer in a pre delivery inspection/walk thru which probably most don't do. If I would have known the trailer needs to be shallow I would have never run mine over the fender.
