Thread from about a year ago. You can see my pictures in there. Was also discussed in the toy hauler section on RV net. Was a problem with the printing process of the stickers. Since you have a 2012 also keep an eye on your cap starting to fade.
Ran into a guy and his wife at the storage facility where I keep my trailer. They have a 2012 Montana. Always covered except when being used and 4 weeks at the dealership getting warranty work done. His is fading. Thought he could use his buffer to bring it back. He wasn't aware of the cap problems in certain years. They were not happy to hear the long term outcome to say the least.
They wife had mention they were in Utah last month and saw more than a few trailers that had the stickers turning red or looking like they were rusting. You are not alone.
