I did search and find an archived reply to this question from another owner in 2014 but I don't think the answers back then were entirely correct.
I too want to remove the decals that shouldn't have been put across the large picture windows of our still new 2015 Maxx trailer. Taking the "style" too far in my opinion by covering the windows.
In the original reply one suggestion was the tried and true and sure to scratch the glass 'razor blade scraper' way, the other was the more modern 'hot air gun' way to heat and remove.
The commenter also warned that using the scraper would possibly remove the dark window tint along with the decal.
I do believe, maybe incorrectly, but it looks this way to me, that the windows are like factory car tinted glass and have imbedded tint and not the aftermarket type of 'stuck on' tint.
And, if it really is an aftermarket tint why would the factory risk having an easily damaged tint on the outside of the glass where those decals live?
Has anyone actually tried to or successfully removed the decals is the real question. Thanks!!!
