The dealer is going to look into it. 2014 350M. Looks like on the right side slide they forgot to put something over the wall to floor joint, and on the left side slide the joint is Covered but apparently has failed. I am in the process of purchasing this unit and found this on a walk around. Dealer states that there is no warranty since it is used even though it is less than a year old and reportedly only used on one weekend before the owners traded for a class A. I gave pictures to dealer waiting to see what they say.
