I bought a huge role of this several years ago to do my 35 foot Pace Arrow motorhome windows. The reflective film allows no one to see inside unless you have a light on and it is dark outside. It's probably going to be a cop magnet. It took me 1 hour per window because it takes for ever to get rid of the tiny bubbles trapped in the film when you install them. Its going to be a cop magnet. I hope not. I did both the driver and passenger windows and intend on doing the front windows over the cab that point up to the Sun at a 45 degree angle it seems. I'm sure it will cut down on the heat.
