If you have any trouble getting the dealer to go over the whole trailer and look for other potential issues I would contact Forest River Warranty Dept and get them to approve of the dealer doing so. Many dealers don't like doing warranty work becasue they don't get paid very well for it. Calling Forest River directly may be what the dealer needs to make sure they will get paid to look this rig over completely.
Info on contact numbers for FR is located at this thread.

Hope this helps in some small way.
