Our Lemon Forest River just squeezed some more juice

In states where lemon laws apply to RVs as well as passenger vehicles, the laws normally only extend to motorhomes. Sometimes the law only applies to the motorized sections of the vehicles. Trailers are normally left out in the cold. I haven't followed the story closely, but, if you haven't done so already, send the trailer back to the dealer to have them resolve all issues. Request that they perform a thorough inspection on the trailer to find other potential problems. You never know where these things will lead so make sure you're following the warranty repair process correctly and documenting everything.
