Since we have purchased our RV we have had several issues with it. Since the first trip the entry door will not stay shut while in transit and continues through today We had requested the dealer check it out but the issue was not remedied. During the time we have owned the RV we have had to have the roof replaced due to poor workmanship at the factory. We had had the TSB for the rear compartment completed however the cargo doors are not aligned properly and one door on the driver side is starting to wear through the aluminum on the side. We have also had the rear cargo door pop open on more than one occasion. We have also had the TSB performed for the improper lag screws being installed at the factory. On one corner of the front of the frame which had cracked they used a 1/8th inch screw with a 1 inch washer instead of a 1/2 by 3 1/2 inch lag screw. The floor in the living room area is dropping up to 1/2 inch at the wall in the front and back of the slides. We have walls starting to separate in the coach as well as the stairs separating from the walls going into the kitchen and the bedroom. There is trim separating from the walls in the bedroom. While this is not the whole list of what is going on it is a good representation of the issues we are facing.
