New owner with big problem

I was in the automobile business with my family for over twenty years and the selling RV dealer didn't have a leg to stand on. You bought the RV in good faith and signed their contract along with their assigned people and took delivery. You would have won in any court and could have sued for damages as well. You still might be able to sue those folks and collect on the trouble and aggravation you went through.

Now if the issue was reversed and you wanted to return the RV and get your money back after delivery they would have laughed at you and said good bye.
