I tinted the windows in my 4500 Trillium
about 4 years ago. I tinted them the same degree of tint that my 30 ft RV has. I don't see a deterioration in the tint and I am extremely satified with them. My wife still can't get used to them. She thinks that you can still see in the Trailer. You certainly cannot during the day and only if you have the curtains open at night. I don't have a condensation problem and clean them just like I would clean my windows on a regular bases.
The tint that I used only has a mild reflection to it. Sometimes I don't know that they are tinted.
Good Luck on your decision.
