I just want to thank you for posting in this. I am going through something similar. Bought a new 2019 Alpine 3801FK. After just 7 months and 2 days I noticed the hallway is bowing, as If the frame is coming up through the floor. Front counter is coming away from the wall, rear undercarriage covering is falling down. Other issues are very serious electrical issues, refrigerator, fireplace, washer (2x) burned out, furnace, a/c, lights, 2 slide outs out of 5 not working properly. Some of these issues are being fixed by the dealership, they have really been good about it. The converter has been replaced and a new motherboard for the command center that controls basically the whole unit is n order. But my concern is the structure of the unit with the hallway. I have to contact Keystone on Monday and see what they have to say about it. I heard something about collateral exchange. I would be satisfied with that. I have owned Rv’s for almost 40 years, both used and new, and never had this happen before. The picture is our kitchen slide out and the flashing code indicates motor #1 and there is a short in the wire. Please keep posing, as I will keep you all updated as well. Wish me luck!
