My 2015 Landmark Grand Canyon started getting tiny paint bubbles on the baggage doors, one propane door, and a small area on the slide. Per 2 different RV body shops they said the cause was a poor prep at the factory. Has anyone else had this or a similar paint problem? The cost of the repair will be around $2,000. I am sure not happy about this since it is a quality control issue emanating from the factory.
