Purchased TT (undisclosed salvage title came in the mail)

So we purchased a travel trailer (2005 Wildwood LE 25EX) from a dealer that does repairs and has been around many many years. They told me they bought it from an insurance company. It wasn't an overly great deal in my opinion (6k) but is solid all the way around and is exactly what we were looking for to fit our family and current towing vehicle. The TT is in very good shape but it's obvious that it has been repaired in the front where the fold down bunk is. It seems very solid, I checked all the inside corners and the floorboard under the bunks. everything works as it should and there are no leaks. We almost got burned on another deal, the last minute we found extensive damage on the floorboards under the rear bunks and walked away immediately. In other words, we are very happy with it. I am sure we will use it for years before we decide to upgrade.

The problem and my worry is that when the title came in the mail, it was orange and states 'flood' under the 'Brand or Legend' section. This fact was not disclosed to us during the sale. Looking over sales agreement after the fact, I am fairly certain I did not over look anything. If this was disclosed before hand, I would have thought long and hard about the deal and probably would have asked for a lot less.

I know we purchased it AS-IS but what gives?? I am fairly certain this practice is considered 'Dealer Fraud'. Is there any thing I should do about this? Also, do I need to call State Farm and let them know? Most likely I will since it seems like the right thing to do.

If anyone has any thoughts, positive or negative please let me know. I guess if anything, I learned that Used Travel Trailer Sellers and Dealers can be shady...

Thanks,
