Wannabe Fulltimers!! How does this 5th wheel look to buy?

I am willing to pass this one up if the unknown damage is a real concern. We could probably be willing to go to 10k for a trailer. I just don't want to pass this one up if it seems to be a really good deal. I received a pm from someone who advised me that we wouldn't be happy in this one due to the floor plan. I am starting to re-think this one. I have until the 13th to make a decision as that is when the owner gets back from his vacation trip.
