Probably a good decision. My windows are Hehr, so no problem tinting. Using the shades or adding awnings would be the way to go now. As I said, you've got a much better window. I'm really surprised that Landmark have gone to an IG unit, or that they are even available in RV's of this price. I had seen them only in really expensive motor homes prior to this. I don't have any percentages of seal failures when the film is applied to IG units but I do know that the mirror tint was far worse than just a dark tint. Most of the major window companies have one or more types of factory tinting now, along with low-e 2 glazing. As a builder in FL I ran into all kinds of problems with windows and tint film.
