Someone needs to be the Devil's Advocate... may as well be me.
Tinted windows are great where the sun shines "hot" a lot. But, it merely means no one can see inside during the day (brighter outside than in). However, at night... without window coverings you are displaying a "window to the world" because now it's brighter inside than out. (Think Naked Show)
Roman shades, pull-aside curtains, day-night shades, etc. all are great for blocking sunlight... and the view. You can see out when fully open, but cannot see out when closed. Here in the Pacific NorthWET, we have clouds more than sun and by gosh I want to see out as much as possible.
Metal mini-blinds rattle and make noise, the downside. The upside, you can crank them slight open and still see out. How to keep them from rattling and banging when you accidentally hit them while sitting at the table or at night when trying to sleep. Perhaps padding the area around the window frame where the blind touches the window may help? Or instead of metal blinds, installing ones made out of PVC or real wood? Below is a picture of another method to keep the blinds hugging the side of the trailer and MAY help with the noise factor.
Everything has trade offs. See out, block the light
... what is important to you?
